Winslet 'won't look' at Titanic 3D love scenes, while James Cameron insists there's more to re-release than cashing in.

Oscar-winners Kate Winslet and James Cameron were at London's Royal Albert Hall on Tuesday (March 27) for the world premiere of the 3D version of "Titanic."

The 36-year-old actress admitted the re-release fifteen years on was a bizarre experience for her.

SOUNDBITE Kate Winslet saying (English):

"It's weird. I mean it is like being forced to go through a photo album of your former self for three and a half hours solidly. It's quite strange you know. But the film is still wonderful and it looks incredible. It's just one of those kind of surreal moments to kind of go with it."

Director James Cameron rejected suggestions thought that the re-release on the 100th anniversary of the tragedy was simply an attempt to cash in.

SOUNDBITE James Cameron saying:

"Yeah, you know look -- there's always going to be people that can piss in the soup of anything good. But frankly I think that remembering Titanic, remembering the history -- that's what the film was there for."

Cameron came to London fresh from the success of his latest venture.

He used a specially designed submarine, called Deepsea Challenger, to dive nearly seven miles below the surface of the Pacific.

"Titanic 3D" will be released worldwide on April 6.
