Johnny Depp is a self-professed fan of the show and has described his cameo appearance in the finale as "... absolutely one of my proudest achievements. No question. It was one of my favourite things, to have been on the last Fast Show."
Simon Day based the Competitive Dad character after a man he saw challenging his two young children in a race at a public swimming pool.
Paul Whitehouse fell over, whilst walking across a field, when filming a Brilliant Kid sketch for the 1st series, which was not scripted. Paul Whitehouse remained in character, by improvising "Fell over, brilliant!" which was kept in.
The Fast Show was only ever intended to be the show's working title, as both Paul Whitehouse and Charlie Higson disliked it. However, the title went unchanged through production and was eventually adopted as the final title.
