The film covers the stubborn response from not only the Reagan administration (Ronnie didn't mention the disease until 1985), and even NYC mayor Ed Koch, who had taken office on Jan. 1, 1978, is single and was thought to be gay by many people (so is California governor Jerry Brown). Koch has actually advanced the idea of filial responsibility in the past.
The film mentions past real establishments in New York City, including the Man's Country Baths. I remember the Everard and the Club.
The basic link for the film, produced by Plan B, is here. Both HBO and 20th Century Fox seem to be distributors. A theatrical run, in arthouse type theaters, is in order (maybe the West End in Washington DC), so that the film could be in the Oscar races. It deserves to be. A good comparison would be HBO's "Angels in America" (Mike Nichols), "How to Survive a Plague" (about Act-UP) and "We Were Here" (set in San Francisco).
