The "movers and shakers" in this weak comedy limned by Charles Grodin do not refer to a religious sect, but the big-wigs in Hollywood who determine how the next many millions are to be spent. Two parallel stories occupy center stage. On the one hand, Joe Mulholland (Walter Matthau) has made a promise to a dying producer that he would put together a film on "Love in Sex." The problem is that there is no script to go with that title -- a minor hurdle by Hollywood standards. On the other hand, Herb Derman (Grodin) is hired to make up the story, but he is neck-deep in marriage woes and will have a hard time holding down his personal life long enough to write. Mixed into both of these tales are parodies of behind-the-scenes Hollywood at its worst. These scenarios are helped along by a fine cast of actors and actresses.
