Zac to the Rescue

That beach better be big enough for all dem muscles.

Zac Efron is joining Dwayne Johnson in the long-gestating Baywatch movie.

The We Are Your Friends star will play a young hothead that teams up with The Rock’s Johnson’s by-the-book character to save their slice of heaven on Earth from a greedy oil tycoon.

They better have these two running in very slooow motion in this one....
