Wally founded Wally Burr Recording.  It was there that he cast and voice directed many shows such as Transformers and G.I. Joe.In 2001 Burr sold his recording studios.

His direction style was very perfectionist, and he would often do many takes of a single line until he thought it had been nailed. This was often very exhausting for the voice actors, who often tell stories of Wally in interviews and the like.

"Union rules allow 4 hours for recording the dialogue for a half-hour show. Overtime must be paid after that time. Based on the assumption that most things (including cartoon shows) can be done better if one uses the allowed time to the fullest, I usually plan to use the full 4 hours. Some directors pride themselves on getting a script recorded in 2 or 3 hours. But the actors are still paid for 4, so I see no point in establishing new speed records when there are almost always scenes or sequences that could be improved by doing another take. And yes, I have a reputation for frequently asking for several takes. I also have a reputation for producing crisp, well-paced, well-acted dialogue tracks."
