Looking for a schlocky B-movie from Halloweens past? Look no further than Classic Cinema, which offers -- I kid you not -- a movie entitled "Bela Lugosi Meets a Brooklyn Gorilla" (watch it! It features Ramona the chimp!). (Sidebar from IMDB: "In his research and preparation for playing Bela Lugosi in Ed Wood (1994), Martin Landau watched this film three times stunned, saying that it was so bad "it made the Ed Wood films look like Gone with the Wind.")
If you really want to make a night of it, you can also take in Dracula, Spooks Run Wild, and The Cyclops!
