The film stars Goran Visnjic ("The Girl With the Dragon Tattoo") as a drugged-out Los Angeles record producer who winds up in jail after a blackout. The catch? He's placed in K-11, the wing of prison reserved for homosexual and transgender prisoners.
The younger Stewart was once attached to star in "K-11" -- perhaps as a transgender prisoner with autism -- but wasn't able to appear due to scheduling issues; instead, she reportedly has a small vocal cameo in "K-11." Keeping with the family vibe, Kristen's brother Cameron also co-stars.
Jules Stewart has worked in Hollywood for 30 years, but this is her directorial debut. At the Cannes Film Festival this week, she told THR that it wasn't easy to make the transition from script supervisor, her previous job, to director.
Still, she's pleased with the results. "The whole point for me is to tell stories that are different and unique, hence 'K-11,'" she said.
Watch the trailer for "K-11" -- which includes some foul language -- above. The film doesn't yet have U.S. distribution.
