Kinsey (2004)

"Kinsey" is the biographical drama that traces the life and research of pioneering sex scientist Alfred Kinsey, unpacking the controversy and cultural upheaval his studies on human sexuality provoked in mid-century America. Laura Linney plays his wife Clara, and the film doesn't shy away from the frank, clinical intimacy that defined the Kinseys' own relationship. There's one scene clipped on the site where Linney bares all, a brief but memorable dose of nudity fitting for a movie so preoccupied with the subject itself.
