The Raven (1963)
Roger Corman was really on a roll with Vincent Price and Boris Karloff. And in this one you get a young Jack Nicholson BEFORE he went insane in 'The Shining', and was some Joker in that Batfilm....
Though this was supposed to be based on Edgar Allen Poe's poem, this turns out to be a bizarre tale which begins with Price gets a strange visit from a raven (what did you think it would be, a Dalek?). Even stranger, turns out the raven is actually a friend who was transformed by Karloff.
Though Price transforms it into Peter Lorre, the whole thing goes wild when they visit Karloff and a battle of the wizards sort of ensues. Not exactly what Poe had in mind, but you have to admit it's better than watching some guy go insane over his lost Lenore.
