Robert Pattinson wants to play a sex and drug obsessed music industry figure in a new movie.

The 'Twilight' star has his sights set on playing fictional record label A&R (Artist and Repertoire) man Steven Stelfox in the big screen adaptation of novel 'Kill Your Friends' - written by former real life A&R man John Niven.

In the book, Stelfox is working for a label in London in 1997 looking for new bands and pop stars to sign while at the same time fuelling his hedonistic lifestyle with cocaine and prostitutes.

A source told The Sun newspaper: "Rob is a huge fan of the novel. He is fascinated by the music industry and is keen to get involved in the project. He's already approached producers telling them he wants to play the leading man. If he gets the role it will be the darkest part he's ever played.

"It's an incredibly adult character and is bound to shock his fan base."

Pattinson is not the only star trying to secure a role in the movie.

Drum 'n' bass artist Goldie - who is parodied by Niven in the tome - has also asked bosses for a part.

If Pattinson does land the lead it will be his latest attempt to move away from the role of vampire Edward Cullen which catapulted him to fame in the 'Twilight' movies.

The 24-year-old actor played a tormented student who rebels against his father in 'Remember Me', and he shared a number of raunchy sex scenes with his co-star Emilie De Ravin in the movie.
