Zac Efron's 'Charlie St. Cloud' trailer: An accident has him seeing ghosts

zac-efron-charlie-st-cloud.jpg Zac Efron decided he was hanging up his dancing shoes for a while ( the "High School Musical" star pulled out of "Footlose" in early 2009) and headed out to sea for a role in "Charlie St. Cloud."

Efron teams up once more with "17 Again" director Burr Stears to play a young accomplished sailor who becomes a caretaker at the cemetery where his younger brother is buried after a tragic car accident. Soon thereafter, Charlie's (Efron) little brother becomes an omnipresent fixture in his life ... as a ghost, "Sixth Sense" style.
