Hey! This is a really really good story, even though I HATE enemy at the gates, I love Moulin ROuge so it all works out. I like how you stayed true to the Moulin ROuge plot (except howthey escaped but it wouldn't be a crossover if you didn't) and I liked how you had Vassil and Christian as old friends because in real life Ewan McGregor and Jude Law are best friends.

OK. Moulin Rouge took place in 1900. Enemy at the Gates took place in 1942-1943. So I think that is a problem.

And...um...well, wouldn't Satine already be dead? I'm afraid I don't understand, maybe all the anacronisms are supposed to be...creative?

Competently written. I haven't seen Moulin Rouge, and so there were a lot of characters mentioned in passing that I've never heard of - the literary equivalent of name-dropping :). I think that you should aim for a more complex plot - at the moment you have a gloomy set of vignettes leading to a random death. Maybe there should be a subtext or a level of irony, or maybe a "plot motor" to urge the reader on. Maybe more of a commentary on the outside world would help. A good example of the "love during wartime" story is "The Unbearable Lightness of Being." Interesting idea that needs development :)
