Jordan Belfort's former business partner is suing director Martin Scorsese over his acclaimed movie The Wolf Of Wall Street.

Andrew Greene is a former executive of Stratton Oakmont, the stockbroking firm set up by corrupt financier Belfort, who was played by Leonardo DiCaprio in the movie.

He has filed a federal lawsuit against Scorsese's production company and Paramount Pictures demanding $25 million (£15.6 million) in damages, according to

Greene, who is said to have inspired the character of Nicky 'Rugrat' Koskoff in the movie, alleges he has been wrongly portrayed as a criminal and a drug-user, and claims the filmmakers did not seek his permission to use his name, likeness or identity.

Koskoff is played by P.J. Byrne in the Oscar-nominated film.
