Directing three Bollywood macho men, two sizzling beauties and one Australian pop diva didn’t seem a tough bet for debut director Anthony D’Souza, but wielding the megaphone for 40 sharks for an underwater action sequence for Blue surely gave him the jitters.

"The scariest part of Blue was in fact the sharks. Getting them to act in my film was not easy," said D’Souza.

The scene with sharks included actors Sanjay Dutt, Akshay Kumar and Zayed Khan, and required a lot of safety measures.

The director explained: "We had shark handlers present on the shoot to make sure that nothing untoward happened. But it was a risky business. Everyone who was around knew that these were living, breathing sharks and that it was their turf."

To perfect the scene, D’Souza brought in Hollywood’s renowned underwater cinematography specialist Pete Zuccarini and James Bomalick of Indiana Jones fame to choreograph the action sequences, but he says it wasn’t because India lacks their kind of talent.

"I would like to make it very clear that we (in India) absolutely do not lack international level talent in Bollywood. The location of my movie was the Bahamas and that required people who had shot in that area. That is the reason technical crew from Hollywood was asked to be a part of the film," he said.

The film, also starring Katrina Kaif and Lara Dutta, has a special appearance by Grammy award-winning singer Kylie Minogue. The director says it was a delight to work with her.

"Kylie was completely a director’s actor. She did what was required of her. She reached the sets ready on the dot; she threw no tantrums and was a delight to work with," he said.
