Being that this is serious movie season for me, I might actually watch Casanova. But I don't know if I can make myself go into a theater next to the theater playing Brokeback Mountain.
If you want to see a movie where they play around with the cowboy myth, it's never been done better than Missouri Breaks or High Plains Drifter.
That Ledger guy is far too bland to play Casanova. You need a weirdo like Depp or somebody similar. In reality, Casanova was more of a con man than a lover. But the manuscript -- which was only found after World War II -- was notorious for the sex scenes. The scams he pulled were much more interesting. Think Jack Sparrow, but in real life.
