Last week, we reported that Steven Sodebergh‘s psychopharmacology thriller Side Effects might lose lead actress Blake Lively because financier Annapurna Pictures didn’t like her in the role. Actresses rumored to replace Lively included Rooney Mara, Michelle Williams, Emily Blunt, and Imogen Poots. Today, Deadline reports that Mara will play the role of “a troubled young woman who develops a dangerous love triangle between her doctor (Law) and her newly paroled husband (Tatum).” The film also stars Catherine Zeta-Jones.
Filming on Side Effects is set to begin in April. The only other role she’s taken since her breakthrough (and now Oscar-nominated) performance in The Girl with the Dragon Tattoo is in Terrence Malick’s Lawless co-starring Ryan Gosling. The Girl Who Played with Fire is slowly moving through the pipeline, but it won’t start shooting until the end of 2012/beginning of 2013 at the earliest.
