David Jason originally wanted to leave the series in 1986, so it was intended that Del would go to Australia with Jumbo Mills. The producers intended to continue the series as "Hot Rod", with Nicholas Lyndhurst in the lead role and all the other main characters. However Jason then changed his mind, so Del decided not to go with Jumbo to Australia.
The outdoor scenes were filmed in Bristol as the producers could not afford the insurance to film in Peckham.
Though not a complete novice, Buster Merryfield had limited television experience before being cast as Uncle Albert, and as a result, he was very nervy in his early days on the show. He used to crash into the audience (deliver his lines without waiting for the laughter to die down) and had to re-record his scenes. He would then dry up and lose his words, and it got to him. So David Jason and Nicholas Lyndhurst sat him down for a talk because he was worried he wouldn't last. If they ever made mistakes in the middle of a recording, they would blame someone and make it into a joke. If you can make the audience think you don't care, they relax and they feel like part of the joke. After that, he cracked his problem, relaxed into the show and the new partnership and became the lovable Uncle Albert.

Lennard Pearce once revealed to David Jason and Nicholas Lyndhurst that as a young actor in the mid 1930s, he was involved in a play that ended up being invited to perform in Germany for a few weeks.

Pearce said he was dumbstruck and didn't know what to say to the Nazi party leader other than thank him.
