Kate Bosworth: Goodnight Moon with Leslie Mann!

Kate Bosworth has joined the cast of Elgin James‘ semi-autobiographical drama, Goodnight Moon. (Elgin started a street gang in the Boston area before ending up at Sundance Screenwriters Labs.)

Synopsis via THR: Juno Temple and AnnaSophia Robb play young girls who find themselves in trouble after they run away to Los Angeles and hook up with skaters and street kids.

Leslie Mann plays Juno‘s mom, a woman who works at a secondhand clothing store but whose best years are behind her. Kate will be Leslie‘s sister.

Chris Coy will play an opportunistic, sociopathic street kid, and Kyle Gallner is a skater; both use the girls to run a scam that goes bad.

Production for Goodnight Moon begins Sunday near California’s Salton Sea before moving to L.A.
