result of having been shot and lit with filmization in mind. The decision to filmize was later reversed, resulting in a negative response to the film-style lighting which came across poorly on the unprocessed video footage. Filmizing success stories include The League of Gentlemen, Spaced, The Office and Heartbeat, all of which can fool most people into believing they were shot on film. On 25 November 2007 an episode of Heartbeat was broadcast without filmizing and the show's producers later admitted this was a post-production error. This error caused alarm amongst the show's fans amidst fears that a permanent switch to video was being made indicating the success of the filmizing technique on this production. The Fox show Arrested Development used an elaborate post-production process to adjust colors and brightness levels to match those of film stock. The 1970s BBC TV show Porridge provides a stark example of the visual differences between film and videotape. The show employed videotape for scenes inside Fletcher's cell, whereas film was used for scenes outside of the cell. The difference in lighting style and frame rate is very noticeable. Many British television series from the 1960s through the 1980s used videotape for interior scenes and film for exterior shots due to equipment limitations. This was parodied in the 'Society for Putting Things on top of Other Things' sketch in Monty Python's Flying Circus'' (Series 2, Episode 5).
