We spotted Rooney Mara on the set of her new film "The Bitter Pill" in New York City today. The actress looks completely different than she has in recent months with long red hair.

Last year she dyed and chopped off her brown hair to film "The Girl With The Dragon Tattoo." She ended up keeping the sharp, sophisticated look. We think the long red hair softens her features and makes her look younger.

Steven Soderbergh directs the psychological thriller starring Mara as a woman who turns to drugs in order to deal with her husband (Channing Tatum) being released from jail. Jude Law also stars. Parts will be filmed in a real prison.
