Bad Girls is a British television drama series created by Maureen Chadwick and Ann McManus and premiered on ITV on 1 June 1999. The series received high critical acclaim immediately following its inception. It was produced by Shed Productions, the company behind its later productions Footballers' Wives and Waterloo Road. The original cast included Simone Lahbib, Mandana Jones, Debra Stephenson, Jack Ellis, Helen Fraser, Alicya Eyo, Kika Mirylees and Victoria Alcock. It is set in the fictional women's prison of Larkhall, and features a mixture of serious and light storylines focusing on the prisoners and staff of G Wing. Eight series and 107 episodes, including a crossover with Footballers' Wives and two Christmas specials were produced and broadcast, concluding on 20 December 2006.
The show featured a large ensemble cast of characters, with only three of the original cast remaining by the series conclusion in 2006. The first series averaged over 7 million viewers per episode, with 9 million tuning in for series 2. Due to a decline in viewers for series 8, ITV cancelled Bad Girls, and the 2006 Christmas special was officially the final episode.
Bad Girls has since been shown numerously in syndication. The success of the series, saw the original series be adapted into a musical, titled Bad Girls: The Musical.
