In 1964, their writing partnership ended, as Muir moved into management with the BBC. Over the next several years, Norden, who had long had a fascination with Hollywood, wrote the scripts for several films, including "Buona Sera, Mrs. Campbell!" and "The Bliss of Mrs. Blossom". Although he was no longer writing with Muir, the two regularly appeared together on panel shows "My Word!" (1956–1990) and "My Music" (1966–1993), first on radio then television. In 1965, he wrote, narrated and starred in a featurette jointly made by the James Bond producers and the Ford Motor Company. The colour short, entitled "A Child's Guide to Blowing up a Motor Car", went behind the scenes of an exploding car stunt being filmed for "Thunderball". Norden takes a young relative on a day out to a film set, where they meet several stars and production team members, but not Sean Connery. Lost for many years, it is now available on the 'Ultimate Edition' DVD of "Thunderball", as released in late 2006.
