Singer/actor Tim Mcgraw is set to return to the big screen in a movie co-starring George Clooney.

The country hitmaker will star in Disney film Tomorrowland, which will hit theatres in 2014.

The movie centres around a science-obsessed boy and an inventor, portrayed by Clooney, as they embark on "a mission to unearth the secrets of a place somewhere in time and space that exists in their collective memory".

This will be the ninth film for MCGraw, whose screen credits include The Blind Side, Four Christmases and Country Strong.
