Ultrasuede: In Search of Halston (15)

Halston, the American dress designer, was so famous in the 1970s that he was namechecked in songs by both Billy Joel ("Big Shot") and Sister Sledge ("He's the Greatest Dancer").

But this documentary on his rise and fall is also interesting for the man behind it, an unknown amateur named Whitney Sudler-Smith who looks a bit like Julian Assange and seems almost surprised to be making a film at all. Still, he gets decent access, kicking off with an interview with Halston's best friend Liza Minnelli, who advises the young man to leave out "the trashy stuff". Nice try. By the end Sudler-Smith is asking one of Halston's coterie, "What's the most fucked-up thing you saw at Studio 54?" The details of his personal decline ("a lotta drugs") are left vague; what's made plain is his professional mistake of signing away the Halston name to a multinational. He died of Aids in 1990, and his archive – oh irony! – now sits in a bible college in Nashville.
