Why, hello there, vulnerable Zac Efron! The trailer for July 30’s Charlie St. Cloud — a romantic drama based on Ben Sherwood’s 2004 novel — has made its way onto the web, and it looks to be quite the star vehicle for the High School Musical actor. If you decide to head to the theater to catch this one, I would suggest bringing along a box of Kleenex. Because you’ll need one to dry your eyes while watching a guilt-ridden Charlie (Efron) attempt to move on after his little brother’s death, and at least three to dab your forehead at the sight of a wet Efron wearing a Henley. See the trailer embedded below!
