LOS ANGELES — A lawyer and investment banker who says he was defamed by a portrayal in “The Wolf of Wall Street” is asking for more than $25 million in damages and the film removed from theaters.

Andrew Greene said in a complaint filed Tuesday against the filmmakers and Paramount Pictures that the toupee-wearing character Nicky “Rugrat” Koskoff was modeled after Greene, whose real-life nickname is “Wigwam” because he often wears a hairpiece.

The film is up for five Academy Awards, including best picture and best director for Martin Scorcese.
