Halle Berry swims with sharks for new film

Halle Berry has been swimming with great white sharks as part of her starring role in new film Dark Tide.

Also starring Olivier Martinez, the thriller sees the actress play a diving instructor who survives a near-fatal shark attack.

However, the movie, directed by John Stockwell, has been criticised by shark experts in Simon's Town, South Africa where the scenes were filmed.

Alison Kock from the Save Our Seas Foundation told the Daily Mail: "After reading the script we decided it was not something we would like to put our names to.

"Our mandate is to try to change people's perceptions of sharks. The first script that we got sounded very much like it had a thriller aspect to it and a personal kind of aspect to it as well."

She added: "But fighting off a shark, or surviving a shark attack - we couldn't see the positive side of that, as much as we tried."
