The programme reveals how Brambell and Corbett were highly dissimilar to their on-screen characters. Corbett felt he had a promising career as a serious actor, but was trapped by his role as Harold and forced to keep returning to the series after typecasting limited his choice of work. Brambell, meanwhile, was a homosexual, something that in the 1960s was still frowned upon and, until the Sexual Offences Act 1967, illegal and was thus driven underground. The documentary went on to describe an ill-fated final tour of Australia, during which the already strained relationship between Corbett and Brambell finally broke down for good.
