Arbogast has a great review of the overlooked and, mostly forgotten, 1988 film, Miracle Mile. You must really go read it HERE.
For years I've been telling people what a great film it is, and THEN I tell them to watch closely for a cameo appearance towards film's end of gay porn star, Steve Hammond. I finally found a rather grainy still to prove my point (below) of Mr. Hammond (on the right) with Miracle Mile's star, Anthony Edwards.
Below that still you can find the poster for another of Mr. Hammond's films.
