According to Rotoscopers, comedian TJ Miller is the first voice actor to join the cast of the Marvel/Disney animated feature,
Big Hero 6. Miller himself took to Twitter to reveal that he'll be providing the voice of Fred, who is described as "an aspiring low-budget filmmaker. He originally volunteered to be a test subject for the the robot experiments by Tadashi, but then stuck around to help the Tech Lab research team with their projects." Miller has also voiced Robbie in
Gravity Falls, and Tuffnut in
How to Train Your Dragon. I'm not familiar with
Big Hero 6, but being the very first animated collaboration between Disney and Marvel to hit the big screen, I'd expect there to be a lot more fuss made about it closer to its release on November 7.
