OK, some 20 years later but the difference between this and that Benny Hill farrago "Who Done It?" I reviewed Wed., is VERY noticeable.
Didn't think I would like this typical 1970s comedy horror fare, but it turned out to be a well-honed funny film written in part by Terry (Dr Who) Nation I believe.
Certainly suited Frankie Howerd who was very good and made for some laugh out loud moments, for e.g. when he slid down the cellar stairs on his backside - "Oooo, well if I haven't broken it, I've certainly bent it"
AKA (my title) "Battle of the Rugs" - between Frankie and main villain Ray Milland.
Most enjoyable.
