The original transmitted version of the sketch included David Walliams as Sydney Newman saying the Doctor could be played towards the end of the series by "any old f*cker with an Equity card". However, this line was edited from the version of the sketch which appeared as a special feature on the DVD of An Unearthly Child (1963) at writer Mark Gatiss's request, because it had caused offence to Colin Baker and Sylvester McCoy, the final actors to play the character in the series before it was cancelled, and he reportedly knew the line was a mistake when he saw it on first broadcast.
