Jennifer Aniston is terrified of getting underwater

Jennifer Aniston is terrified of getting underwater. She had difficulties during the swimming scenes in movie Cake because of this.

She said at a special screening of Cake in Los Angeles "I basically have a real fear of going underwater."

"As a kid, I drove my tricycle into the pool and [now] I can't go underwater."

"To get the one shot of me going under with the weights, I think we did that 30 times. It was the hardest day of my life."
