Agnes Bruckner (Vacancy 2: The First Cut) is joining Madeline Zima (“Californication”) in director Jamie Babbit’s upcoming homicidal lesbian thriller Breaking the Girl. The 26-year-old starlet replaces Brit Marling (Another Earth) as Zima’s lover and partner-in-crime.

The film follows two girlfriends who plot to kill each other’s enemies. Babbit, who directed Elisha Cuthbert and Camilla Belle in the highly underrated psych-thriller The Quiet, is working from a script by American Psycho scribe Guinevere Turner.

Breaking the Girl costars sexy starlets Tiya Sicar (“Vampire Diaries”), Kate Levering (“Drop Dead Diva”) and Shanna Collins (The Haunting of Molly Hartley). Vagina-less players include Shawn Ashmore (Frozen), Manish Dayal (“90210”) and Sam Anderson (“LOST”).

Bruckner is best known to fright fans for her starring roles in Sony Pictures No Vacancy 2: The First Cut and Dimension Films’ Venom. Other creds include AfterDark’s teen slasher Kill Theory, the Sandra Bullock snore-fest Murder by Numbers, and Lifetime’s “The Craigslist Killer.”
