I thought Color Me Kubrick was very good. Here, John Malcovich plays Alan Conway, a real-life confidence man who went around England posing as Stanley Kubrick, and getting all sorts of favors from people mesmerized by being in the presence of such a great film director.
Alan Conway was gay and John goes crazy with that detail. Before you can say "camp" John is already coning men all over the place and flaming it all up. Don't believe in any review that calls John's performance in Color Me Kubrick anything less than perfect. He rocks.
As to the gay content, and there is a lot of it, I initially thought that the light on the gays was not positive; after all they are all either duping people (John's character) or being duped. John's character is all wrong, he is basically an inconsiderate drunkard bitch from hell.
Still, and I don't really know why -- maybe I just liked the movie so much, I didn't really sense homophobia exactly, the duped gays were dumb (but so were the few straighties and hooligans who fell for Conway's lies) but they seemed like nice people for the most part, dumb nice people. In any event, the movie and the plot don't allow you enough time to create any sort of emotional attachment to anyone, and you'll like it like that.
Color Me Kubrick is as much about the cons of a crazy gay as it is about two former employees of Stanley Kubrick (Brian and Anthony) who wanted to make a movie filled with inside jokes, Kubrick movie references, and joy. And that, they did.
