Sky Television originally made two TV movies with the Dr. Martin Bamford character from Saving Grace (2000), called Doc Martin (2001) and Doc Martin and the Legend of the Cloutie (2003). Martin Clunes' production company signed a six-film contract, at two films a year for three years, but Sky Pictures folded after the first two were completed. Clunes then took the concept to ITV, who liked the basic idea but wanted it to be more than just a "fish out of water" story. So, the Doctor's back-story and personality were changed. It's possible the name change came about for copyright reasons.
