[1] It has often been noted by those who worked with him that Camfield always retained an affection for the army and brought military standards of organisation to the programmes he subsequently directed.
[2] His directing credits included Doctor Who, Z-Cars, Paul Temple, Public Eye, The Lotus Eaters, Van der Valk, The Sweeney, The Onedin Line, Blake's 7, Shoestring, The Professionals, Out of the Unknown, The Nightmare Man, the BBC dramatisation of Beau Geste, and Ivanhoe, the 1982 television movie.
He is particularly well known for his work on Doctor Who and was production assistant on its earliest serials, both the pilot and broadcast versions of An Unearthly Child, and Marco Polo.
[9] Shortly after directing The Seeds of Doom, Camfield was commissioned by Philip Hinchcliffe to write a four part serial for Doctor Who in 1976.
In 2013, as part of the fiftieth anniversary celebrations for Doctor Who, the BBC produced a drama depicting the creation and early days of the series.
