For Vince, Eric, Drama, and Turtle, life in Hollywood’s fast lane can be an intoxicating ride. In fact, Eric and Vince have taken on risky new roles — as producers — in Season 4 of HBO's hit comedy. After making financial sacrifices to become producers of Medellin, Eric and Vince approach the only director who can make the film on a shoestring budget: auteur Billy Walsh. But will Billy’s on-set antics and artistic insecurities make them critical darlings . . . or will they be booed out of theaters? Adrian Grenier, Kevin Connolly, Kevin Dillon, Jerry Ferrara, Jeremy Piven, and Perry Reeves star.
