A few thoughts: Not only is this movie not very good, it's not even the best ensemble horror comedy of 1963. That's a very specific thing to not be the best of, and The Raven owns that title by a landslide. Vincent Price is usually much more entertaining than this, and the same can be said of Peter Lorre and Boris Karloff. For being a comedy, I don't recall laughing a single time, with a majority of the "jokes" slipping by without me even realizing if was supposed to be funny. Basil Rathbone is pretty much the only one here who has any decent material, and he does what he can but isn't in the movie enough to make it worthwhile, and a majority of his "funny" moments come from his recitations of Shakespeare. My kidneys just may rupture from the outpouring of laughter. With a cast this great, a talented director (Jacques Tourneur), and a writer as prolific as Richard Matheson, I expected more. And that's right, the same Richard Matheson who wrote the book I Am Legend, over a dozen Twilight Zone episodes, The Incredible Shrinking Man, House Of Usher, and oh, whaddyaknow, The Raven. What a horrible waste.
Who would I recommend it to? People who want to see a cast of greats in a cornball horror parody might get a kick out of it, but I got no kicks.
