Boo

I've just come across Boo as an extra on the DVD of Frankenstein (1931) and, due to the fact I was watching it at well past midnight, I found it as strange as it was funny. It starts off with a bearded man with a strange expression on his face emerging from a jack-in-the-box and holding up the film's title, which is a weirdly disconcerting effect, particularly as I have no idea who this man was. The narration is rather outdated, not so much because it was recorded in 1932, but because of what is said (the reference to woman automobile drivers is ever so slightly sexist), but what I don't get is, while Universal included footage from its movies 'Frankenstein' and 'The Cat Creeps', the Dracula segments actually come from F.W Murnau's 'Nosferatu'. This seems strange, because I would have thought the studio would want to publicise its own, then-recent, Dracula movie (the one with Bela Lugosi). To conclude, Boo is an oddity that you probably won't find yourself watching unless you get the Frankenstein DVD, which you ought to own anyway
