Disney's $4-billion purchase of Marvel in 2009 almost immediately sparked speculation that Pixar Animation might develop lesser-known comic properties like Ant-Man, Power Pack and even Doctor Strange.

When the deal was announced, Disney CEO Robert Iger conceded that possibility had been discussed. "Pixar boss John Lasseter talked to the Marvel guys about this and they all got excited about it," he said in a conference call. "We think there’s ultimately some exciting product that come of that. Sparks will fly!"

But fast-forward two and a half years, and it appears any thought of an on-screen collaboration between Pixar and Marvel has been rejected.

"I'm chief creative officer of Disney Animation as well, and with Pixar it's like, 'Keep doing what you're doing, guys,'" Lasseter tells IGN.com. "It's a filmmaker-driven studio. All of the ideas come from the filmmakers themselves. Working with the filmmakers on ideas."

When pressed at to whether there's any possibility of that kind of team-up between the corporate siblings, Lasseter replies: "No, not at Pixar. We have The Incredibles, so we've done superheroes here ourselves and so we have that kind of history with Brad Bird doing The Incredibles."
