"I'm not a very cynical guy, but I like doing cynical films. This was one that felt like there was none of that and sort of clean of all those kinds of things. I thought it would be fun to do," Clooney said in a statement.
In the film, Clooney plays a jaded, surly, reclusive scientist who was once a wide-eyed boy genius. He teams up with a curious teenager who has a thirst for the scientific world.
Their adventure gives a look into the future, including both the good and the bad. The answers for a better world may exist in this other worldly place called Tomorrowland.
The 54-year-old actor is part of the action in this movie, but he says he's no longer the "guy" who hits away.
"I used do in my 30s, I would do a film with some action in it where I get to punch some guy, knock him out and walk away. Now, I'm the guy that gets punched and dropped," Clooney said.
"Tomorrowland" will hit theatres on May 22.
