Kate Mara and her sister, Rooney Mara, are set to share the screen for the first time in their acting careers in the upcoming Werner Herzog-directed film Bucking Fastard. The actresses will play twin siblings Jean and Joan Holbrooke, who are so close to each other that they speak in unison, love the same man, and have the same dreams. Speaking exclusively with PEOPLE at the Los Angeles premiere of Imperfect Women, Kate described the experience of shooting the film with Rooney as "very special." She also shared that the project brought her and Rooney closer together.
