James Stern’s Endgame Entertainment will co-finance with Private Defense Contractors the Steven Soderbergh-directed ‘Bitter Pill.’ The film stars Rooney Mara, Jude Law, Channing Tatum and Catherine Zeta-Jones. Megan Ellison’s Annapurna Pictures had originally been expected to finance, but that became shaky in the past few weeks. That gives the film new funding and a new titles. The film was originally titled Bitter Pill, but was retitled Side Effects, before going back to Bitter Pill. Open Road is releasing domestically.
