Tim McGraw appears in the new movie Tomorrowland, but doesn't appear in the new trailer. That shouldn't stop you from watching it, though, since it's definitely interesting.
And don't worry if you find yourself confused by the trailer since Tim didn't understand it either. He told Rolling Stone Country recently:
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.
It's a huge production; there's a lot going on. All the stuff I hear back, it's going to be spectacular.
Tomorrowland is expected to hit theaters May 22, 2015.
