The Scrooge Puppet is a character not technically its own character, being puppeteered by the Hobo in the movie to scare the main protagonist. In the video game adaption however, he is his own character, playing the main villain in the train sequence who steals all the tickets from the children so they won't be able to reach the North Pole.
Tom Hanks, like his other roles, plays the character who is played by another character really well; being as loud, boisterous and frightening as can be.
Jim Hanks shows off more of his range by not directly imitating his brother, but I feel like the scare factor was severely stripped, leaving the character as some grumpy old a-hole without going full ham with his performance. The delivery and performance itself sounds especially abysmal comparing his work here to his otherTomroles. Not a fan. Sorry, Jim.
