Thanks for pointing that out Dickles.
I seem to recall that the director of M.O.P.I., Gus Van Sant (?) had a conversation with River about his character. From what I recall at the time, River told him that he wanted his character to not just be a very close friend to Keanu Reeve's character, but to actually profess his love for him. That was
not in the script. River felt that it would make his character much more authentic and believable. After much discussion it was decided that his character would actually fall in love with his co-star's character. It did add much more depth and layers to the storyline. It was scandalous enough that two supposedly straight actors were playing gay characters in the U.S. in 1991. And gay prostitutes at that. But the fact that it became a semi love story between the two was even more controversial at the time.
Both actors took a real chance of ruining their future careers by taking the roles in that film. Back then that was a very risky and courageous move for the sake of art and their craft.
It reminds me of another story about Matthew Broderick. He gained much of his early fame in 1981 by playing David, the twink lover of Harvey Fierstein in the original off-Broadway play Torch Song Trilogy. When it was apparent that the play would be made into a feature film in 1988, Fierstein of course offered the part to Broderick. Broderick almost immediately accepted it. His managers told him that it would or could be career suicide to play a gay character in a major film. I heard they strongly advised him against it. And finally, at least warned him of all the potential pitfalls.
Broderick stood his ground. His reasoning was that the play had given him his first real big break in the business and that he wouldn't have the success he already enjoyed without it. The way I understand it, Broderick felt it was a duty and a privilege to be able to play the character of David on the big screen. Maybe he even felt that he owed it to Fierstein. He did an absolutely phenomenal job in the movie. I can't imagine anyone else playing the role any better. The character of David stayed with me for many years. As we can see from his very successful career, Broderick did not suffer for taking on the film role.
