What would you do if your husband fell in love - with another man? "Making Love" is about Zack (Michael Ontkean) and Claire (Kate Jackson) - two attractive, successful and playful affectionate partners who share the perfect marriage. He's a medic. She's a TV exec. And they're about to buy an absolutely gorgeous Beverly Hills home. Enter Bart (Harry Hamlin). He's a gay writer whose striking good looks pepper his social life with enough one-night stands so that he easily avoids commitment. When they first meet, Zack is merely curious. Gradually, he decides to take the plunge. Less about homosexuality than self-discovery, "Making Love" tackles the fundamentals of life - pain, loss, recovery - with astonishing sincerity and candor. Some critical scenes - such as when Zack tells Claire what's really happening to their marriage - are handled with a sensitivity rarely found in American movies. Highlighted by touching performances, "Making Love" really probes the depths of passion - in all of us.
