Halle Berry vomited on Olivier Martinez's shoes when they worked together for the first time on 'Dark Tide' because she was sea sick.

The couple met while working on drama 'Dark Tide' and the Oscar-winning actress - who plays a shark naturalist whose life spirals out of control following a tragedy at sea - admits she initially struggled with sea sickness.

She said: "My first day on the boat I'm not ashamed to say I got terribly sea sick - I threw up about five times, but it never happened since. I got my sea legs and have not been sick one day since.

"But that first day there were very high waves it was very choppy. Half our crew was chucking up. I couldn't help it but I threw up on Olivier's shoes!"

Halle admits working on the film was a huge "challenge" because the cast and crew were in such a confined space, which meant preparation was difficult.

She added: "We are out there in the middle of nowhere on a little boat and on most days there are around twenty men and women on that little boat trying to make a movie, with all these tight corners, in a very constricted space. Which is an acting challenge - something I had to learn how to do.

"We had to find a little corner and deal with what ever the process is at that time, and sometimes we couldn't prepare at all but just have to hit the deck running."
