Much has been written over the years regarding the 'one-note" performances of Marsha Mason. Four of these "one-note" performances earned Mason Oscar nominations and IMO this is the best of those four. ONLY WHEN I LAUGH is Neil Simon's big screen re-working of his own play THE GINGERBREAD LADY. Marsha Mason plays Georgia Hines, an actress recently released from rehab, trying to get her career going again, trying to re-establish a relationship with her daughter (Kristy McNichol) and trying to stay sober and not really doing a great job with any of them. Mason hits all the right notes here and makes Georgia a flawed and realistic human being. Some of Mason's best moments involve no dialogue at all...there is a wonderful scene about 2/3 of the way through the film where an on-the-edge Georgia is walking the streets of Manhattan around dusk and it seem like every other storefront she passes is a bar. She then stops at an interior pay phone to call her doctor from rehab; however, he is not present and Georgia doesn't want to talk to the doctor who does answer the phone. This scene is extremely well-played by Mason and I think it's the scene that probably nailed the Oscar nomination for her. Kristy McNichol charms, as always, as Polly, Georgia's self-sufficient daughter who still yearns to be Mommie's little girl sometimes. James Coco and Joan Hackett also deliver Oscar nominated performances as Georgia's best friends, Jimmy, an unemployed actor and Toby, a vain, society beauty trying to cope with the fact that her best years have passed her by. Hackett is particularly impressive as the fading beauty whose fragile ego doesn't keep her from kicking Georgia in the ass when she needs it. Though Simon definitely has stronger screenplays under his belt, ONLY WHEN I LAUGH is worth seeing if for no other reason, the strong performances by the four leads, three of which earned Oscar nominations.
