For housewife Pat Kramer, it was a day like any other in the ’80s idyll of Tasty Meadows, with its ranch houses and manicured lawns. But then suddenly she begins experiencing a most unexpected side effect from life in this consumerist paradise. The products that she uses every day, and that her ad exec husband (Charles Grodin) sells to America, have caused her to grow inexorably smaller, and soon her doll-like stature becomes a media sensation. Jane Wagner’s script, an inspired feminist riff on 1957’s The Incredible Shrinking Man (playing in a new restoration at NYFF57), proves an ideal platform for Lily Tomlin, particularly her gifts for physical comedy, which play brilliantly at every scale.
