Cohen is a partner at the Gersh Agency, which is one of Hollywood’s oldest talent agencies. Previously, he worked on Wall Street, per his bio.

His pivot to Hollywood came after he moved to Los Angeles and started working in film, collaborating with actors like Dustin Hoffman, Kate Hudson and Goldie Hawn.

“I started out as an investment banker in New York, made my way to L.A., financed some movies for people by accident so I learned how to make movies because I invested in a movie and turns out the producers didn’t understand they weren’t supposed to the the money home,” he shared during a talk at the Toronto International Film Festival in 2015. “So I took the movie over, learned all about film production, started a production company with Dustin Hoffman, made a lot of movies.”Cohen is a producer
