Auntie Mame once insisted that “life is a banquet, and most poor suckers are starving to death.” That sentiment is echoed in a new documentary about a nonfictional Mame, Susanne Bartsch, who reigned in New York during the post-Warhol era. Raised in Switzerland where she felt “very boxed in,” she created party scenes (“more like full-scale theatrical events”) in London, Tokyo and, especially, New York. When the AIDS era hit, her parties became fundraisers. Her costumes are outlandish and her attitude is pure diva — but her frivolity has a worthy nonconformist agenda behind it. Directors Anthony&Alex will attend the screening. (4:30 p.m. June 9, Egyptian) — J.H.
