The 65-year-old 'Avengers' star said that his character Frozone is likely to appear in the sequel of the hit animated series, reported Digital Spy.
Pixar recently announced that a follow-up to the 2004 animated comedy, which was directed by Oscar-winning director Brad Bird, is in the works.
"Every time I run into Brad, he always tells me Frozone is part of what's going on, so I have to believe that," Jackson said.
"I guess they could be the Incredibles without Frozone, but I think Frozone would be a wonderful addition to what's already there," he added.
