The two-time Oscar winner is best known for "Finding Nemo," "WALL-E" and his work on the "Toy Story" movies.
"John Carter" sounds like a film you'd think is for teenage boys and die-hard sci-fi fans, but Stanton sees it differently.
"Look it. I'm an immature 40-year-old romantic. That should kind of hit every demographic, shouldn't it?" Stanton said.
When it comes to the world of "John Carter," Stanton is looking to the future for the film's real success.
"What's going to make you actually take that movie off the shelf 10 years from now, five years from now, 15 years from now? That's the game we've always been in," Stanton said. "So, I could really care less exactly how it does right now. I want it to do well enough that, you know, maybe we can all get to do our jobs again. But my bigger goal is, I know that if you do watch it, whenever you watch it, you'll be glad you did."
"John Carter" tells the story of a Civil War veteran who is somehow transplanted to Mars and forced into battle.
Taylor Kitsch of "Friday Night Lights" fame plays the title role and Stanton says he worked him hard.
"It was such a tough job. He was in almost every shot of the film and it was a really punishing role physically. But, you know, kudos to him. He put up with it and it really shows off on the screen," Stanton said.
"John Carter" is rated PG 13 and also features Lynn Collins and Willem Dafoe.
