Few Holocaust documentaries have the pedigree of Genocide, which rises above literally hundreds of similar productions thanks to soulful narration from Orson Welles and Elizabeth Taylor. There are few insights here that you can't get in slicker productions (and in fact, some of the minor details mentioned in the film are in dispute), but the steady pace and penetrating focus on the Jewish experience in WWII makes the film definitely worth checking out. The film notably won a Best Documentary Oscar, to boot.
