Leo And Co At Wolf Of Wall Street UK Premiere

Leonardo DiCaprio and his co-stars in The Wolf Of Wall Streethave walked the red carpet at the movie's London premiere.

And the cast have again defended the controversial movie's explicit sex scenes and the drug use by the unsavoury banker Leo depicted on screen.

Margot Robbie, who previously appeared in Neighbours, told the BBC: "It's a story of extremes.

"To downplay those things would defeat the entire story. You can't do a story about addicts and not really show how enticing drugs and sex were for this person.

"The audience wouldn't understand why this person got sucked into those things if you couldn't show them how fun it could be to do drugs and have sex with hookers and make it look awesome - at least for the first half of the film.

"It was important to have the second half of the film where you show the drastic ramifications of those actions, so that you can show people that we obviously don't condone that behaviour."

The premiere in London's famous Leicester Square drew a host of home-grown celebs, including I'm A Celebrity... babe Amy Willerton, model Daisy Lowe, magician Dynamo, Peaches Geldof and Ashley Roberts.

The Martin Scorsese-directed movie opens in the UK on 17 January.
