This could be off-topic (but might not be as it might be Hammer) and Im hoping someone will remember this.
Could be a film, could be an episode of something. Set and made in 1970s. A couple buy a house in the middle of English countryside (dream house). They buy some kind of voodoo doll and it starts doing weird stuff (as they do

). I know this sounds like any number of films but does it ring any bells with anyone? I think the male lead was fairly famous (maybe Ian Ogilvy? or someone who looks like that anyway). It could easily have been an episode of Tales from the Unexpected or something like that.
Any help much appreciated. Im sure someone here will recognised it (or something like it!)
