It has made it into the top 30 of Britain's Best Sitcom. Starring Judi Dench and Geoffrey Palmer, it follows the relationship between two former lovers who meet unexpectedly after not having been in contact for 38 years.

The new title was taken from the 1931 Herman Hupfeld song "As Time Goes By", and the recorded version by Joe Fagin was used as the title music. The show was created by Colin Bostock-Smith with produced and directed by Sydney Lotterby and was written by Bob Larbey, who had co-written both The Good Life and Ever Decreasing Circles with John Esmonde. In 2004, As Time Goes By was ranked No. 29 in Britain's Best Sitcom. The series was produced by Theatre of Comedy Entertainment, in association with DLT Entertainment Ltd. for the BBC.
