Vince Vaughn conquered his phobia of sharks on his new movie.

The Hollywood actor was a nervous wreck swimming in shark-infested waters while filming 'Couples Retreat' - but managed to overcome his lifelong fear.

Vince, who was filming off the Bora Bora coast at the time, said: "I grew up around a lake so I was uncomfortable with what might be lurking in the water.

"There were sharks and we swam with them. It's like anything in life. Once you get around something, you go, 'Oh this is kind of cool.' But, originally, I was like, 'There's no way I'm going in the ocean with a shark.' "

Vince - who used to date Jennifer Aniston - has also admitted he hates mobile phones.

The 39-year-old star refuses to buy one and will borrow a phone if he needs to make a call.

He said: "It's become a problem for me with pay phones becoming extinct. I drive the people around me mad by using their cell phones. I just started to email which I like but cell phones drive me mad. I'll never own one unless I absolutely have to."
