It has been decades since this film, to my knowledge, has been broadcast on British Television. Probably so to stop giving ideas to conniving families, but from what I can remember, it is one of the funniest "black comedies" I have ever seen. If I remember correctly there was a long winded scene involving a poisoned tea-bag which poisoned the wrong person, also when the elderly batty cousin digs out some old cheque books with large amounts paid out in the past, suggesting that as they paid out well before, then surely the cheque book would still be usable. I would relish seeing it again and would sincerely hope it would actually be as funny and enjoyable as I last remember it. See it if you can.
