 THE BOYS IN THE BAND (1970)
From: Boy Culture

Music plays a major part in the opening of William Friedkin's 1970 adaptation of Mart Crowley's controversial stage play, The Boys in the Band—a camp rendition of “Anything Goes” ushers us into the action, and its lyrics are transparently indicative of the content to come.

Also noteworthy is the film's use of a number of highly intelligible yet silently mouthed words that precede Kenneth Nelson's exclamation, uttered when he barely misses a phone call. In fact, the first clear sentiments expressed—albeit soundlessly—come from an irate truck driver, whom it's safe to say is shouting, “Motherfucking asshole!” at Frederick Combs in the tunnel.
