What an odd film. A few decent chuckles, a few wonderful camera tricks, but far too much chitchat and a very nasty sadistic tinge.
The "old dark house" thriller idea is hardly given any new energy, and the thunder sound effects often swamp the dialogue, making some sequences a challenge to endure. I agree with other reviewers that this feels like a 70s version of the 30s, with the same costume/lighting ideas as many of the 70s Agatha Christie adaptations (and Olivia Hussey in the cast).
Wilfred Hyde White is great fun from beyond the grave, and a special word for the wonderful sequence where the usually glorious (but here slightly subdued) Beatrix Lehmann walks behind his projection screen, appears on screen, then emerges from behind the other side. Also, a very effective sequence where Ms Lehmann talks about her late employer with her face reflected in his photo.
Far too many characters I found it hard to care about, all written in very poor, sub-Cluedo dialogue. Even Honor Blackman struggles with the poor material she is given. Some sequences are, frankly, silly. Edward Fox leaps through a window instead of knocking on the door. After relating the saga of the escaped loony, Mr Fox instructs everyone to lock up the house and hide in their rooms; this comes despite his having rendered the house insecure by destroying the lounge window.
There is a nasty tinge of sadistic enjoyment to the final sequences, where the barking mad murderer is cornered in his lair. As much of the rest of the film tries (and very occasionally succeeds) in being light-hearted, the unpleasant conclusion, followed by a twee little "happily ever after" coda, seems at odds with the film's intentions.
Very uneven and unsure of whether to laugh or scream, this really isn't very good.
