Leonardo DiCaprio laughs at Titanic appearance

Leo couldn't stop laughing at how young he looked in the 1997 blockbuster.

Titanic may have made bonafide stars of its lead actors, Leonardo and Kate Winslet, but the film's director James Cameron has revealed that Leo thought his appearance hilarious upon seeing Titanic 3D.

'When I watch the film now they look like such babies,' explained Cameron. 'I sat with Leo in Sydney not long ago and I showed him 18 minutes we had converted. He just couldn't stop laughing at himself as kind of a kid.

'Leo has gotten much more rugged-looking while Kate's beauty has evolved in such a great, striking way,' he continued to Culture magazine.

'The way I relate to it is that it's a snapshot in time and their characters Jack and Rose almost exist as fictional characters independent of who Kate and Leo are.'

Titanic 3D is in cinemas now.
