Mesmerising and incredibly brave performance from Al Pacino. On one level, it's a classic 'cop goes under cover to catch a killer' story, on another it raises some disturbing questions about society's attitude to gay men and gay sex, and how gay men themselves act out the hatred dished out to them from parents and society. Real NY fetish clubs and punters were used in the movie and it shows. Although the movie is set very much at the end of the 70s, it is remarkable how little things have changed. Yes, poofs are now acceptable on prime-time TV, as long as no one has to think about them having sex, and certainly not without a condom. Julian Clary almost got crucified for mentioning fisting on TV. This is a great movie. Apparently, Marc Almond's favourite film. The sort of film that gets better and deeper each time you watch it.
