Jamie Chung is one of a number of beauties signed on for Zack Snyder's Sucker Punch.

In a recent interview with E! News, the actress spoke on the training she's been undergoing for the shoot, courtesy of... Navy SEALs?!?

"We have Navy SEALs doing physical training, and then we have stunt and fight choreographers from Watchman and 300," said Chung, who will play Amber in the action-packed fantasy movie. "It's going to be awesome."

But forget fighting. Chung added that she's most scared about a different aspect of the film: singing.

The actress and costars Vanessa Hudgens, Abbie Cornish, Emily Browning, Carla Gugino and Oscar Isaac have already begun recording tracks for the movie, which sounds like a combination of a number of genres.

"I have to say that's the most terrifying part, because I don't sing," she said. "I'm working on it, but just because I'm Korean doesn't mean I karaoke."
