Walt Disney as Mickey Mouse
The father of Disney didn't just come up with the idea of Mickey Mouse.
Walt Disney also provided the voice for him in several animations, including Fantasia.
Michael Caine as Finn McMissile
Michael Caine lent his British accent to the Cars 2 detective, Finn McMissile.
While watching the movie you might not realize that the tough, fearless detective was brought to life by this blockbuster star.
Julie Walters as The Witch
Julie Walters doesn't just play a witch in the Harry Potter movies.
She also does a wonderful job as the crazy, wood-carving obsessed witch from Brave.
Demi Moore as Esmerelda
Everyone's favorite dancing gypsy from The Hunchback of Notre Dame got her sultry voice from Demi Moore.
Is it just us did Disney model Esmerelda's features after Demi as well?
Billy Crystal as Mike Wazowski
We can all thank Billy Crystal for the spunky, uptight lime green monster, Mike Wazowski.
Without his humor and vocal talent the Mike we all love wouldn't be the same.
John Travolta as Bolt
John Travolta is just as good at voice acting for Bolt from the movie Bolt as he is at dancing.
We loved watching him dart around the screen, and it made us wish he did more voice work.
Tom Hanks as Woody
The beloved toy, Woody, was brought to life by Tom Hanks in Toy Story.
His brother, Jim Hanks, also voiced Woody in the Toy Story video games.
Oprah as Eudora
Turns out this gift-giving, inspirational TV host also plays the loving mother, Eudora, from The Princess and the Frog.
One thing's for certain, we would love to have Oprah as a mother.
Matthew Broderick as (Adult) Simba
The prince of the '80s also happens to be the prince (and then king) of the Pridelands.
Broderick's work as the adult Simba in The Lion King is arguably his best.
Jane Lynch as Calhoun
You might recognize Jane Lynch from her comedic roles, but she also did the vocals for Calhoun from Wreck-It Ralph.
Her rough sound is the perfect match for this tough soldier.
