Dive Into Zac Efron’s Shirtless ‘Charlie St. Cloud’ Clip (VIDEO)

The upcoming Zac Efron drama Charlie St. Cloud didn’t just provide the former High School Musical hunk with an opportunity to expand his acting chops, it also gave him a chance to try out new activities.

But the best part? Efron’s physical feats, such as diving, sometimes required a healthy dose of shirtlessness. 

Check out the video below to see Efron rise (or is that sink?) to the challenge and look good doing it. Charlie St. Cloud is in theaters Friday.
