NOSFERATU
I'm not positive, but I'm pretty sure this is the first full-length silent movie I've seen. LOVED IT. If you're reading this, then you probably already own it or scan Harry Knowles' column at Aint It Cool News to get DVD recommendations. If by chance you haven't seen it, it's a testimony to the high quality that old movies were capable of. (A thousand apologies for ending a sentence with a preposition).
