A Is for Acid is a 2002 British television film based on the life of the serial killer John Haigh, known as the Acid Bath Murderer because he dissolved the bodies of six people in sulphuric acid. Haigh, hanged in 1949 for his crimes, had wrongly believed that murder could not be proven without the presence of a body. Starring Martin Clunes in the lead role, the film was shot in Scarborough, chosen because its appearance was believed to be similar to that of London when Haigh lived there during the 1940s, and also Saltaire to represent his early life. The film was produced by Yorkshire Television for the ITV network and aired on 9 September 2002. Directed by Harry Bradbeer and written by Glenn Chandler, A Is for Acid also featured among its cast Keeley Hawes, Richard Hope and Celia Imrie.
