the best of the collaboration between karloff and lugosi . the production value be high and karloff makeup be excellent . there be a lot go on it the script perhaps too much and a the script be a bit confusing and sometimes pointless . but the atmosphere be thick and the aura hang over the movie like a dense mist . there be more horror imply than actually see . this movie have black magic and a man skin alive and treachery and phobia and and a chess game with life at stake . mostly and it have great performance by karloff and lugosi in their one and only film appearance a equal ( without one dominate the other ) . truly and this be one of the fine universal horror classic and will deliver everything a fan of such fare could possibly want .
