I watched the film, "The Detective" over the weekend on Kanopy. I chose it because it is a slight film-noire starring Frank Sinatra. I like Sinatra's acting.
The film has good acting and script. What I found interesting was its handling of homosexuality in New York at that time (1968). The film mildly addressed the bigotry faced by gay men from the police then in a factual way, and via Sinatra's role it was portrayed as wrong.
Wikipedia has a good synopsis of the film HERE.
I recommend it.
