Tim McGraw is gracing the silver screen with a small role in Disney's upcoming film Tomorrowland.

The family adventure flick revolves around a former boy genius (George Clooney) and curious teenage girl Casey Newton (Britt Robertson) who set out on a mission to unearth the secrets of an unknown place and save the world in the process. Their goal is to uncover the mystery of a place known as Tomorrowland, which exists somewhere in time and space.

McGraw plays the role of Casey's father.

"There's not much I can say about it because I read the script, I acted in the movie and I still don't understand it," the country singer tells Rolling Stone jokingly. "It's a huge production; there's a lot going on. All the stuff I hear back, it's going to be spectacular. "

McGraw has a decent resume as an actor, having previously appeared in the movies The Blind Side and Country Strong, but he says the biggest challenge is finding the right role to accept.

"I get a lot [of scripts]; it's just finding the right thing for the right time," he notes. "It's got to be something that moves me. As an artist, you've got to have a visceral reaction. If you have to think about it, it's probably not the right thing."

The country star appears alongside Clooney, Robertson, Hugh Laurie, Judy Greer and Kathryn Hahn in the film. Tomorrowland was directed by Brad Bird (Mission: Impossible — Ghost ProtocolThe Incredibles). It's scheduled to hit theaters on May 22.

Soon after, McGraw is scheduled to hit the stage at both the 2015 Taste of Country Music Festival and Country Jam Colorado, which run June 12-14 and June 18-21, respectively.
