Screenwriter Mardik Martin, who penned classics including Raging Bull and Mean Streets, has died.

The writer, who was a frequent collaborator with Martin Scorsese, passed away in Los Angeles on Wednesday at the age of 82. The news was confirmed by fellow screenwriter Howard Rodman on Twitter.

"My friend and colleague Mardik Martin died this morning. You may know him for his writing in Mean Streets, Raging Bull, New York, New York. To say that Mardik was one of a kind is a wild understatement. No one-no one-will ever fill those shoes. May he rest in well-earned peace," he wrote alongside a picture of the pair smiling.

Though of Armenian descent, Mardik was born in Iran and raised in Iraq, and worked for a film distributor as a teenager. He later moved to the U.S. to study economics at New York University (NYU) and met Scorsese in 1961.
He went on to work with the Oscar-winning director on his early short films, and later collaborated on Scorsese's feature debut, Who's That Knocking at My Door? and his documentary Italianamerican.

He also co-wrote 1973's Mean Streets with Scorsese and New York, New York with Earl Mac Rauch.

Mardik spent almost two years researching boxer Jake LaMotta for 1980's Raging Bull, starring Robert De Niro, and his screenplay with Paul Schrader landed the pair a Golden Globe nomination.

"De Niro wanted to make Raging Bull, but Marty didn't (because) he hated boxing and sports," Mardik told the Los Angeles Times in 2007.

He later served as a writing professor at NYU and USC's School of Cinematic Arts, while his last screenplay credit was for Fatih Akin's 2014 film The Cut.
