Desi Arnaz Jr. plays Kenneth Magee, an American writer who makes a best with his publisher, Sam Allyson (Richard Todd). His ego is great enough that he thinks that he can write something on the level of "Wuthering Heights" (which he doesn't hold in high regard) in 24 hours. At stake is $20,000 of his money. So Sam procures for him a Welsh manor named Baldpate where Kenneth can supposedly write in seclusion. Of course, nothing goes as planned, and Kenneth is interrupted all night long by a family looking to exorcise their old demons and a man looking to purchase the manor.
This effort by the cult filmmaker Pete Walker ("Frightmare", "House of Whipcord") is notable mostly for uniting four legendary horror actors: John Carradine, Vincent Price, Peter Cushing, and Christopher Lee. "House of the Long Shadows" is a must see for their work, if nothing else. Walker and this fine cast does seem to have fun with the material, which was meant to be played with a sense of humour. Certainly some of the tropes of the genre are present and accounted for: the dark, stormy night, the locked room, the old family secret, etc. What this viewer appreciated most about the film was the old school atmosphere of a classic "Old Dark House" type of story, and for the fact that Walker and screenwriter Michael Armstrong so completely manipulate their audience.
While this viewer didn't dislike Arnaz Jr. as much as most people who've seen this, the less that is said about his performance is still probably better. But don't see it for him. See it for Price (who rattles off the exposition in style), Lee, Carradine, Cushing (whose comic performance is simply wonderful), and Walker regular Sheila Keith (who plays Carradines' daughter).
Good fun for fans of the genre.
Seven out of 10.
