Ha! I was right about the Hanks Brother voicing Woody! IMDB lists Jim Hanks as the voice.
Nobody is currently credited with Mike Wazowski. If that's not Billy Crystal, whoever it is did a fantastic job! Fred Tatasciore is a buddy, so I'll ask him next time I see him if he did Sully since he's listed as "rumored".
Toops, IMDB lists Elizabeth Daly as the voice of Mrs. Incredible. I think you're right as it really sounds more like Holly Hunter, so maybe IMDB is in error? Odd, but still. Awesome to have as many of the Pirates cast back, but Pintell & Raghetti don't sound quite right, maybe the actors were out of practice from not being in the last movie
