You’ve probably heard a lot about The Runaways, the upcoming biopic about the 70′s Joan Jett-fronted, all-girls rock band. After all, based on the cast alone, the Floria Sigismondi directed film is already quite compelling — Kristen Stewart, best known for her work in Twilight, has been tapped to play Ms. Jett, Academy Award-nominated actor Michael Shannon will fill the role of “Svengali” Kim Fowley, and Dakota Fanning, who is apparently no longer eight years old, has been cast as Cherie Currie.

But for the role of some other high-profile musicians, filmmakers tapped a real life band to play the part. St. Louis garage rockers Living Things will appear as none other than The Ramones in the upcoming film.  According to an issued press release, in the scene, which is shooting this month, The Ramones are playing at Rodney Bingenheimer’s notorious English Disco nightclub in Los Angeles circa 1975. Living Things have already recorded a cover of “We’re A Happy Family” for the scene.

The Runaways is expected to hit theaters in 2010. Currently, Living Things have reverted back to being Living Things and plan to support their latest studio album, Habeas Corpus, with an appearance at Lollapalooza next month.
