Cameron Diaz and Jason Segel star as a husband and wife whose sex life has gone stale in Sex Tape , out Friday. The film follows their characters, Annie and Jay, respectively, as they try to “get it back.” In an attempt to find their lost libidos, the couple embarks upon a three-hour odyssey to conquer and record every move described in Alex Comfort ‘s book, The Joy of Sex , but they are then faced with a new dilemma: their “sex tape” has synced to the cloud, subsequently uploading onto numerous iPads that Jay has–of course– distributed as gifts to friends. Critics have generally delivered scathing reviews.
