Johnny Depp is to make a cameo in 'London Fields'.

The 50-year-old actor will make an appearance alongside his girlfriend Amber Heard - whom he has been dating for over a year - in the upcoming adaptation of Martin Amis' 1989 novel, according to The Hollywood Reporter.

Billy Bob Thornton and Jim Sturgess also have confirmed roles in the thriller, but it is not yet known who they are playing.

The movie is set in bleak 1999 London and follows the story of a psychic (Heard), who has visions of her death and goes on a hunt in an attempt to track down her killer.

Shooting kicked off last month in the UK capital, and it is believed Depp has already filmed his role after arriving in London for Rob Marshall's adaptation of 'Into the Woods' and 'Mortdecai'.

Amis has adapted the screenplay along with Roberta Hanley, while Matthew Cullen is directing.

Muse Productions is producing alongside Demarest Films, Hero Entertainment and Geyer Kosinski's Media Talent Group.
