Given how corny these movies are, you gotta figure that they must have had fun making them. The movie focuses on a house that strangely accommodates whomever lives there. The inhabitants were: author Charles Hillyer (Denholm Elliott (with hair!)), who gets haunted by one of his own creations; Philip Grayson (Peter Cushing), who gets a little too close to a wax statue; John Reid (Christopher Lee), whose daughter's cuteness is apparently a facade; and actor Paul Henderson (Jon Pertwee), on the verge of getting a little too much into character.
"The House That Dripped Blood" is actually worth seeing (well duh; it stars Peter Cushing and Christopher Lee). Aside from just being neat, there might be some undertones: it might be calling into question the issue of real horror vs. assumed horror. Like in "The Shining", we might ask whether the house/hotel itself holds some memory of past events. And if absolutely nothing else, Ingrid Pitt (as Paul's co-star) is HOT HOT HOT! Around the time that this came out, she also starred in "Countess Dracula" and "The Vampire Lovers" (also with Peter Cushing). Maybe she - like Barbara Steele - will remain known only as a scream queen, but mark my words: SHE IS A HOT SCREAM QUEEN! I'd like to see Ingrid Pitt and Barbara Steele co-star in something.
I guess that the only weird scene (so to speak) is where Denholm Elliott is wearing a pink shirt and fluffy jacket. You read that right. What kind of a name is "Denholm" anyway? Oh well. A very cool movie.
