Sid James grew to dislike the series and fell into a deep depression towards the end. He increasingly looked back at "Hancock's Half Hour" as the quality part of his tv career.
As of 2024, Sally Geeson is now the only surviving member of the original regular main cast.
Producer/Director William G. Stewart would marry Sally Geeson when the series ended in 1976 (following the sudden death of Sid James). They eventually divorced in 1986.
Despite being set in Putney, South West London, the exteriors of the Abbot's house were actually filmed in Howard Road, New Malden, Surrey, which is about six and a half miles from Putney. The multi storey car park next to New Malden railway station is also clearly visible in the background during the opening credits. The interior scenes were filmed in front of a live audience at Thames Television studios in Teddington, Middlesex, which was just over four miles away from New Malden.
Sid James was initially very pleased that the show was an instant and solid ratings hit. He prophetically said to co-star Diana Coupland "This is it. If we don't screw this up then this gig should see us out". He was happy at the regular and reasonably well paid work, the financial security it offered and that the production schedule afforded him to continue doing other film and stage work as well. However after the third series he started to grow despondent at the diminishing quality of the scripts and was secretly hoping that the series would be cancelled allowing him an excuse to move on. Yet the show continued until his death in 1976.
