Thundercats Thundercats


Comparision of the voice over actors who have been the voice of Mumm-Ra with sound clips and images.
Franchise: Thundercats

Mumm-Ra is perhaps one of the most famous villains to come out of the 80s and had a huge part in making ThunderCats the huge cult success that it has become.  Mumm-Ra had two forms. Most of the time he had a decrepit old body most resembling a mummy from ancient Egpyt. However, when he uttered the famous lines, "Ancient Spirits of Evil, transform this decayed form to Mumm-Ra THE EVER LIVING!", he would become a gigantic muscular villain that is easily one of the scariest we have ever seen!

I definitely am split down the middle with all of the old vs new voices in this franchise. Some of the characters I definitely like the 'new' take on their voice while others pale in comparison to the originals.

With this one I honestly can respect and admire both takes for this epic villain. Robin Atkin Downes does a great job in capturing the classic lines but in the end he just does not sound quite as decrepit as I like my Mumm-Ra to be. Earl Hammond wins this one easily for me. I will be interested to see which way I go with future characters though!

I'm giving Hammond this one. He hams it up (pun unintended) and I love it.

This is my favourite role from Robin, so he easily earns my vote.

Robin Atkin Downes= Creepy & Whispery

Earl Hammond= Hammy & Boisterous

Robin Atkin Downes takes the cake.

Earl is the most iconic yes, but iconic doesn't necessarily mean the best, like how Hamill is the most well known joker when I think there are some that are just as good if not a little better. It's the most well known performance, but the campiness while funny, can get a little irritating after a while.

Robin fits much more how the character should've been I feel when I picture a decrepit old mummy sorcerer. Downes whispery rasp is just chilling, and it is one of Robins best performances IMO. He adds this creep factor to the character that wasn't really all there in the original (Which yes I know that was the campiness and he did have a couple good moments at being creepy)

While Earl is the most iconic, I have to give this to Robin hands down.

Both are awesome. I think of them as nearly equal. Earl Hammond is my favorite though by a tiny amount.

I say this VC is down to which version you prefer.

Earl was excellent in the older cartoon. He sounded really dark. Not the most natural performance to me, but it's real iconic.

Robin was fantastic in the newer version. His quieter voice downright creepy, and effective for the role.

I dislike having to choose between these two, but I'll be taking sides with Robin here.

Robin Atkin Downes is vastly superior over Earl Hammond!Robin's vocal performance as Mumm-Ra is the best thing about the new Thundercats and is easily the strongest vocal performance in the entire show to date.

I prefer Robin Atkin Downes. His whispery voice appeals to me more than Hammond, who just sounds like a typical villain.
said at 12:56 AM on Wed Sep 28 2011
Downes is pretty good but Mumm-ra is one of those crazy roles where an actor can really have fun and go all out and have it still fit the character! I do not understand why Earl Hammond isn't winning! He is perfect! That voice is fantastic! One of my favorite villain voices of all time!

 4 Shout Outs! is Earl Hammond NOT winning this? He made Mumm-Ra one of those great 80s cartoon villains, right up there with Skeletor and Cobra Commander.

Downes is very good, but Hammond is iconic.

Earl's voice greatly reflects the campiness of the 80s series, but Robin's voice greatly reflects the natural anime-like approach for the new series. That's pretty much the case with all these Thundercats voices.

I'm not biased to the old show at all, I liked Friedle's take on Lion-O better for instance. But, with Mumm-Ra, I'm going with Earl Hammond. He MADE the show for me among all the campyness it had. But, I enjoy Downes' take all the same.

I haven't watch either show so my judgment is 100% neutral.
Hammond have sinister and strong voice, but it don't feel natural.
Downes have even more sinister and calculating voice what really fits character like Mumm-Ra. Downes voice also feel really natural.

My vote goes to Downes

Earl Hammond takes it, all the way! And it's not just because it was the 80s and it was so over the top. It was also because of the character itself. I mean, Mumm-Ra was a decrepit, moldy mummy who turned into the Hulk (more or less). He had to play Mumm-Ra as both a senile and dangerous old man and a rampaging monster.

Now, as of yet we haven't heard Robin Atkin Downes' version of Mumm-Ra the Everliving. And I think if it's half as creepy and sinister as his Mumm-Ra the Mummy, i think I will like it.

But it will be hard to top Hammond's crazy, cackling bag 'o bones!!

About time the ThunderCats came! And what a compare this is! Personally, I do like how Earl captured the essence of Mumm-Ra, but honestly, Robin does it for me! Granted, he has much more to work with since the principal voice cast for the remake are rather well-known and probably have seen the original series, themselves.

And another thing: I'm not actually afraid to say that the remake is better than the original, because in my eyes, it rather is. Not to bash the classic version, but if you take off the nostalgia glasses, the only thing notably great about it was the theme song and the fact that Larry Kenney voiced Lion-O! Simple as that. The 80s show had more of a cheeseball take (*ahem* SNARF AND THE THUNDERKITTENS!) and maybe little to no continuity. As far as I know, the remake could be the real deal, as long as Cartoon Network gives it the right direction... However, knowing the TV network, they'll just cancel it to make more room for mediocre animated shows and borderline stupid live-action, again.

@Ninjaman15 While I completely agree that up to this point I like the remake better....what some people don't understand is that 80s was all about over the top and cheeseball takes - that doesnt make it bad just makes it hard for people to stomach who have gotten used to newer trends etc. People now expect continuity and while I love a series with continuity you have to appreciate the other side of the coin when stacked up to shows like them.

Once, again I agree that the new series is better, the overall voice cast is better etc etc I just hate it when people write off 80s stuff as cheesy commercials that only people viewing through nostalgic glasses can appreciate. 80s was the best decade of animation ever and the only one that comes close to matching it is the 60s!
said at 1:40 PM on Tue Aug 16 2011
@OptimusSolo Yeah, you must be right, but then again, I knew how the 80s went off. I actually enjoyed the original ThunderCats from soul, to the point of having a maximum amount of flopping (I did this as a child, pretty much for my Autism, but that's not the point). You also made me realize another thing: I expect continuity, but not to the point where stupid crap like Naruto or Sonic X get overboard... At least a tiny bit of it is what I want, not as a whole.

And of course, how do you think Captain N and G Gundam were like? Over-the-top cheese fests that some would hate or actually enjoy... Captain N is out of that area because of those pathetic changes made and how it makes most of us play more video games, so only G Gundam is the one thing you can tolerate with cheesiness... And maybe the original ThunderCats, if you're gonna be sentimental, anyway.

One more thing: even if opinions are opinions, you're really unable to label the past as "the best" when it comes to facts because, well, it's like this for me: music was great in the past and I prefer that to nowadays where you have these cheap artists like Rebecca Black... But I'm not referring to all music from the past.
OptimusSolo (Admin)
said at 2:27 PM on Tue Aug 16 2011
@Ninjaman15 what do you mean 'when it comes to facts'?? I will explain why the 80s is the best further in the forums if you want with data to support it - I don't want to clog this page to much further.

As far as my other point I just think continuity makes such a difference that you can only compare continuity based shows to each other and then non-continuity based to each other. Transformers G1 was basically non-continuity for the most part as were most of the other action shows of the 80s (he-man, g.i. joe, m.a.s.k., thundercats, silverhawks) so its fair to compare those to each other as well
said at 2:46 PM on Tue Aug 16 2011
@OptimusSolo Exactly. You should more likely compare continuity-based things to each other, and non-continuity based stuff to each other as well... Because if you scramble it up, then it really would be a big problem (not that logic really matters, anyway)

And if you do explain how the 80s is the best, it just goes to show that opinions are taking place as we speak... And that's common since saying EVERYTHING as a fact is pretty immature, honestly. Also, if the whole world had interest in the same things altogether, then we'd be dull, boring, and half-hearted machines... Therefore, I think really all of us like different things, but in terms of how we act, being treated equally is the way I see it.

While I do enjoy Hammond's marvelously over-the-top performance, Robin is easily the better of the two. Note how he seems to savor every line in his mouth, clearly enjoying his performance, and as a result when Mumm-Ra goes louder, it has more impact.
OptimusSolo (Admin)
said at 9:29 AM on Tue Aug 16 2011
@SpiderDreamer I obviously disagree. To me each line of Hammond's is more convincing whereas Robin makes him sound to 'young' and 'limber'.
said at 7:08 PM on Tue Aug 16 2011
@OptimusSolo My main problem with a lot of these comments is that people are only comparing the VOICES and not the ACTING. Hammond is probably one of the better actors on the old show, I'll grant that, but he still sounds pretty cartoony.

Robin, by contrast, is an excellent actor who can certainly do menace, and I find it all too appropriate that he makes Mumm-Ra sound younger and more limber, if only relatively.
OptimusSolo (Admin)
said at 7:36 PM on Tue Aug 16 2011
@SpiderDreamer Good points for sure and I agree with you. That is why some of the future ones you will see me lean towards the newer voices. I would say that Kenney is a way better character actor than Will though. Really the only good character actors in the old show were Kenney, Hammond and Hyman. What do you think?
said at 7:54 PM on Tue Aug 16 2011
@OptimusSolo Eh, I thought most of them had pretty solid voices, but their acting left a lot to be desired.
OptimusSolo (Admin)
said at 11:21 PM on Tue Aug 16 2011
@SpiderDreamer That strikes me - Hyman especially was one of the most esteemed actors of his generation!
said at 7:17 AM on Wed Aug 17 2011
@OptimusSolo Hurm... somehow I doubt he was more esteemed than the likes of Frank Welker, Michael Bell, Jack Angel, Corey Burton, etc.
said at 9:34 AM on Wed Aug 17 2011
@OptimusSolo OK, I did a little more research on Hyman, and you're right, he was quite the esteemed character actor. I'm willing to blame his just-OK performance (as I call it) in Thundercats on poor voice direction. The same goes for Larry Kenney; after all, look at how good he was in the new series with the great Andrea Romano doing the voice direction!

OptimusSolo (Admin)
said at 2:32 AM on Tue Aug 16 2011
@partymonster411 You are missing my point - It seems you are looking at things subjectively rather than objectively. If you were to say 'I like the new series better' or 'i like the designs or storyline of the new series better' that is a very valid opinion and I would have no problem with it.

But to make a blanket statement that 'i like all the old/new voices' makes it seem like you are just saying that because you like that series better and you have not actually analyzed each of the voices.

I find it hard to believe that any one person who looks at it objectively would honestly say EVERY old voice or EVERY new voice is better.
said at 2:34 AM on Tue Aug 16 2011
@OptimusSolo or maybe i find Robin more scary or menacing, Will more young, Matthew more snarky, and Kevin....well its KMR. and Cheetara more sexy. The kittens are mutual i like the new ones as much as the old one
OptimusSolo (Admin)
said at 2:37 AM on Tue Aug 16 2011
@partymonster411 Thats fine - I find Earl Hammond way scarier than Robin but I have no problem with you liking Robin only with you liking every 'new' version. I stick with what I said before. My biggest issue is you liking KMR over Earl Hyman...I am one of the biggest KMR fans there is but that just blows my mind! (that and liking anyone better than Larry Kenney, but lets leave those discussions for when I do those compares ;) )
OptimusSolo (Admin)
said at 2:39 AM on Tue Aug 16 2011
@partymonster411 Also, sometimes I try to separate and judge based on the vocal performance and not the character design and what was dictated to them by the powers that be. It wasn't Will's choice to make the character younger etc. So, I try to separate that when I judge the overall performances. Although, I can see why it would play a part in your decision.

@partymonster411 Well it should have because it was epic how he came in and everything --- But Earl Hyman has one of the greatest voices I have ever heard in my entire life. Granted he was just using his natural voice but he just has one of those voices that is way to epic to sweep under a rug here!
