I can't believe Matthew Lewis's The Monk has never been made into a movie. It's the first book on my list for the RIP Challenge. There's so much happening! Murder, kidnapping, lust, thievery, subterfuge, sorcery -- the list just goes on. Can't you just imagine what Peter Jackson or James Cameron or Francis Ford Coppola could do with material like this?
Ahem. This is why you're supposed to do research before you write the post. Turns out there is a movie version of The Monk; looks like it was a joint production of Spanish and British film companies. Not sure of its quality (only a 5.0 on IMDB, but that's only with 17 votes). And Netflix doesn't even carry it. Still, it would be interesting to see how someone translated this great Gothic tale into film.
