Zac Efron: Shirtless Swimming Scenes!
The 22-year-old actor shot scenes in a massive underwater tank. “It takes up pretty much the whole stage,” Zac explained. “Underwater, there’s this system…but you can actually hear voices underwater! I have no idea how it works,” he laughed.
“It’s a lot of stuff you wouldn’t have to expect you have to deal with,” Zac continued. “When there’s elements involved like swimming through murky water, getting a certain piece of your vest snagged, very precise movements…it’s hard to hold your breath!”
FYI: The video contains a plot point spoiler for the movie!
