I had some slight interest in seeing Casanova. When I heard that the actor was one of the leads in 'Bareback' Mountain, I lost all interest. It will sting, at least for a while.
There's really no way to do Casanova on the screen. Fellini tried and got fouled up. If you want to know more about the guy, read portions of History of My Life (Willard Trask translation).
I will not see this film either and after reading this review I consider this movie to be a horrifying sex show. Actors Heath Ledger and Jake Gyllenhaal have lost my confidence of ever seeing them in a movie after the immoral acting display they did in this movie.
