Was Andy Warhol a bottom? The documentary A Walk Into the Sea: Danny Williams and the Warhol Factory brings us closer to the horrible truth. Its a pity we know less about Warhols onetime boyfriend and undiscovered avant-gardist Danny Williams, who may or may not have drowned in the summer of 66. Forty years later, Williams niece, Esther Robinson, tries to shed light on the mans abbreviated life, providing what may be the toothiest exposé yet into the soul-sucking modus operandi of Warhols Factory. The filmmaker never knew her uncle, but she comes to understand him as something of a kindred spirit of Edie Sedgwickwhich is to say, a better person than Warhol. The doc is accompanied tonight and Sunday by a separate program of Williams own short films. Documentary at 7 and 9:15 p.m. tonight through Wed., Dec. 12. Shorts at 8 p.m. tonight and Sun., Dec. 9.
