I've been listening to the characters for some time now and I'm wondering if they're using the original voice cast or someone who is doing a convincing impression?
I'll list the ones I know.
Mr Incredible: Craig T. Nelson:
Mrs Incredible: Holly Hunter
Violet: Sarah Vowell
Dash: Spencer Fox
Mirage: Elizabeth Pena
Rick Dicker: Bud Luckey
Edna Mode: Brad Bird
Syndrome: Jason Lee
Ralph: John C. Reilly
Vanellope: Sarah Silverman
Anna: Kristen Bell
Elsa: Idina Menzel
Lightning McQueen: Owen Wilson
Mater: Larry the Cable Guy (what kind of name is that? )
Holley Shiftwell: Emily Mortimer
Woody: Tom Hanks
Jessie: Joan Cusack
Buzz Lightyear: Tim Allen
Jack Skellington: Chris Sarandon
Rapunzel: Mandy Moore
Since these are professional actors and this is a job, they would have to pay them to come in and record the voice overs.
Did Disney Infinity have the funding to rehire all the original cast members to reprise their roles?
I'm assuming some would be easier to rehire then others, Chris Sarandon for example.
This is because voice artists (as opposed to actual real life actors) always seem willing to reprise their best roles at the drop of a hat.
Even Jodi Benson (Ariel) kept practicing the voice to keep it good, even if she wasn't playing that role.
I'm assuming the Frozen sisters could have done it differently, they would have known going into it, okay, you're going to be in a computer game, so here's some additional voice recording to do for the game.
That is, of course, if production of Frozen and Disney Infinity was happening at the same time.
