Widely considered the first "commercial" or "commercially released" gay feature film ever made in the U.K., where the story was directly about gay relationships and themes, but which was not about crime (blackmail or murder), or purely stereotypical.
Filmed around the Notting Hill area, Holborn, Hammersmith (driving past the church near the Hammersmith Apollo) and Earl's Court. Jim the main character can be see in several scenes driving up Pembridge Road towards The Gate Cinema which was the first U.K. Cinema to show the film (where it had a very successful run before transferring for a further run in central London). The Gate recently showed the remastered version with a Q&A with the director Ron Peck. (July 2017).
There is a follow up documentary (Strip Jack Naked AKA Nighthawks II) which gives more detail on the real life bars and clubs and an insight into the London Gay Scene (much different to any other Gay scene in the U.K. at that time) with narration by director Ron Peck. It also includes several deleted scenes which in my opinion would have made the original film much more compelling and a more accurate portrayal of what the Gay Scene was about at that time.
The film was 'X' rated at the time of release which is something it's director Ron Peck was unsure of at his recent Q&A at the Gate Cinema (July 2017). In the follow-up doctumentary from 1991. Vintage photo's clearly show the film on the billboard for the Gate Cinema from 1979 which an 'X' certificate.
