Rumour one of our own here had a minor role in playing one of the prison inmates is just a rumour, allegedly

"The Governor was a ITV television drama series that began in 1995 and ended in 1996, with just two series being broadcast. It was devised and written by Lynda La Plante, known for her hit television series Prime Suspect, which went on hiatus in the same year. Each episode of The Governor was forty-five minutes long, with the exception of the first episode which was double-length. La Plante felt that the series had reached a natural end and decided not to write any further episodes, thus meaning the last episode was broadcast on 27 April 1996. The series starred Janet McTeer and Derek Martin as prisoner governors Helen Hewitt and Gary Marshall respectively. The complete first series was released on DVD on 28 March 2011.[1] The complete second series was released on 4 June 2012.[2]"
