Speaking to Entertainment Weekly at the Producers Guild Awards, Chase said: "It is in the early stages, I am just writing. It is about rock 'n' roll, but that is about all I am comfortable saying at this point."
Chase has previously voiced his desire to move away from the Mafia world he explored in HBO's The Sopranos. "He's been there, done that. He's moving on," an insider earlier told Variety.
Chase signed up to write, direct and produce the untitled film for Paramount last year.
