Jekyll is a British television drama serial produced by Hartswood Films and Stagescreen Productions for BBC One. The series also received funding from BBC America. Steven Moffat wrote all six episodes, with Douglas Mackinnon and Matt Lipsey each directing three episodes. The series is described by its creators as a sequel to the novella Strange Case of Dr Jekyll and Mr Hyde, rather than an adaptation of it, and the Robert Louis Stevenson tale is used within the series as a back story. It stars James Nesbitt as Tom Jackman, a modern-day descendant of Dr. Jekyll, who has recently begun transforming into a version of Mr. Hyde. Jackman is aided by psychiatric nurse Katherine Reimer, played by Michelle Ryan. Gina Bellman also appears as Claire, Tom's wife. Filming took place at various locations around southern England in late 2006. The series was first transmitted on BBC One in June and July 2007, receiving mainly positive reviews.
