Diablo Cody
Brooke Busey-Maurio (born June 14, 1978), better known by the pen name Diablo Cody, is an American writer, director, and producer. She first became known for her candid memoir, "" (2005), and the blog that preceded it. Later, Cody achieved critical acclaim for her debut feature film script, "Juno" (2007), winning awards such as the Academy Award for Best Original Screenplay, the BAFTA Award for Best Original Screenplay, the Independent Spirit Award for Best First Screenplay, and the Writers Guild of America Award for Best Original Screenplay.
Ricki and the Flash
Diablo Cody based the script in part on her mother-in-law Terry Cieri, who has fronted a New Jersey bar band for years. Cody said, "I watched her on stage so many times, and I thought to myself, 'This woman's life is a movie.' Cody specifically wrote the role of Ricki with Streep in her mind noting that actresses over 50 in Hollywood typically don't get complicated parts. Streep's costar is played by her real life daughter, Mamie Gummer marking the third film the two have made together, after 1986's "Heartburn" and 2007's "Evening"."
