Murphy's Law is a BBC television drama, produced by Tiger Aspect Productions for BBC Northern Ireland, starring James Nesbitt as an undercover police officer, Tommy Murphy. Since 2003 there have so far been five series of the drama, shown on BBC One. The first three series were composed of individual stories, and series four and five were each single stories composed over three episodes. The show is based on the novel of the same name by Northern Irish author Colin Bateman. The initial episodes played off Nesbitt's persona that the public were used to from the series Cold Feet but as the series has developed the stories have become more dramatic and darker. A sixth series has not been commissioned. In a 2008 interview, Nesbitt attributed this to the fifth series' ratings being damaged after it was scheduled opposite ITV's popular drama Doc Martin.The Cybermen are a fictional race of cyborgs who are amongst the most persistent enemies ofthe Doctor in the British science fiction television series, Doctor Who.
