Rooney Mara was joined by her costars Channing Tatum, Jude Law, and Catherine Zeta-Jones for the New York premiere of Side Effects last night. She wore a white Alexander McQueen dress and Nicholas Kirkwood pumps while Catherine donned a black lace Michael Kors frock. Catherine's husband, Michael Douglas, walked her down the red carpet, which included visits from some of New York's fashion elite, like Donna Karan and Rachel Roy. Kate Mara joined her sister, Rooney, at the event after Rooney attended Kate's House of Cards premiere on Wednesday. It's been a busy week for the duo, who have both been doing press for their two new releases. Rooney attended a Side Effects Q&A with director Steven Soderbergh and Jude in the Big Apple earlier this week and Kate made the party rounds for her new series in DC and NYC. House of Cards hits Netflix today while Side Effects will open in theaters on Feb. 8.
