Zac Efron has more than a few awkward moments in his new movie, "That Awkward Moment." In one, he's fully nude, stretched out horizontally on a toilet. In another, he wears an X-rated costume to a party where his date's parents are in attendance.
But being naked on-set came with its own strange costume, Efron said. "There was, like, a sock thing," he said Tuesday, according to People magazine. "It fell off. You just cup your hands."
"High School Musical" made Efron a teen idol in 2006, but fame hasn't been all smooth sailing since then. According to People, he completed a stint in rehab earlier this year.
Efron said that his family was what helped him get through tough times. "My family's my rock," he said. "I know they're not going anywhere."
Efron stars with Miles Teller and Michael B. Jordan in the romantic comedy, which opens Jan. 31, 2014. Efron also stars as a young doctor in "Parkland," the new movie about the assassination of President John F. Kennedy.
