The Real Guy Behind A 'Wolf Of Wall Street' Character Is Suing For $25 Million

"The Wolf Of Wall Street" character Nicky "Rugrat" Koskoff was known as a toupee-wearing, drug and hooker-using party animal who took part in illegal business activities.

But Andrew Greene - the real head of corporate finance at Stratton Oakmont on which the "Rugrat" character is based - is arguing in a new $25 million lawsuit that his on-screen portrayal is now damaging his professional reputation as an investment banker.

Greene, played by actor P.J. Byrne in the film, is suing director Martin Scorsese's production company and Paramount for $25 million over his on-screen portrayal, claiming the movie is defamatory by showing him as a criminal, drug user, as well as mocking his premature hair loss, according to documents obtained by TMZ.

Greene argues that the filmmakers never got his permission to use his name, likeness or identity. While the character is nicknamed "Rugrat" in the blockbuster, Greene was called "Wigman" by his real-life coworkers.

In the film, some of the character-in-question's antics include him shaving the head of an employee, who, in exchange, is rewarded with $10,000 for breast implants as well as having sex with an employee in the office.

"Not only does he want $25 mil in damages from Paramount and Scorsese's production company," adds TMZ, "he also wants them to hand over all copies of the film ... and yank it out of theaters. Good luck with that."
