Randall and Hopkirk (Deceased)

Randall and Hopkirk (Deceased) is quite a curiosity, isn't it. I have come into the great riches of the complete box set - 21 hours of television, I am not sure how many episodes, let's just say A LOT. I have watched the first two 'eps' and part of one of the commentaries, with Annette Andre who played Jean Hopkirk. Someone is kind of interviewing her and she keeps saying 'I don't really know', or 'I don't remember', or 'Oh yes, he was a really nice man'. Well why would she remember, it was 35 years ago or more. They are all pretty good actors though, putting on quite a music-hall romp really, without music but with slapstick and the whole silliness of Randall always talking to Hopkirk while other people are in the room who, of course, can't see or hear him. 'Will you be quiet!' 'I didn't say anything' 'Um, er... see you later' etc. It reminds me a bit of Mr. Ed and Wilbur's relationship, not that fulfilling, though obviously Hopkirk is a better detective as a ghost than he was as a live human. I imagine that by the end of the series Randall is a millionaire, if not they should go to a casino and Hopkirk can just tell Randall what's on people's cards. I'd do that for a friend if I was a ghost.
