Serious doubt has been cast upon the authenticity of this documentary, since being broadcast in 2002. A lot of the statements made by the people interviewed, have been largely contradicted by members of Harry H. Corbett's family. According to the biography by Susanna Corbett about her father, there wasn't very much in the way of actual hatred between the two leading men of "Steptoe and Son."
There hasn't been another documentary about this classic sitcom, which the fans would welcome.
