I feel bad about offering this up for you without checking it out myself, but I'm seeing the film next week, and I don't want to spoil a frame of it for myself.
Then again, I'm already sold on this one. Jean Dujardin is an actor I truly admire and enjoy, and I love the "OSS 117" comedies he made with this director, Michel Hazanavicius. When I heard they were making a silent black-and-white film together, I was intrigued right away. The only reason I didn't see this at Cannes this summer was because of an unfortunate bus schedule. I've been doing my best to be patient since that point, and it's killing me. I'm very pleased it's going to be at Toronto, and I'll have a review for you from that festival.
In the meantime, though, if you want to take a look and just get an idea if this is something you're interested in or not, you can check out the trailer over at iTunes, where it is an exclusive premiere. Or you might not, because the people I know who have seen the film say that trailer almost ruins the entire movie.
