There is two, actually, played by Michael Praed and Jason Connery, in Robin of Sherwood, which remains the most imaginative and definative rendering of the legends on television. Each played Robin from two different standpoints: The two extant legends from literature and folklore, one the native British peasant and the other the dis-possessed Saxon noble man.
The more recent BBC effort has no real basis in the folklore tradition and gives less than a cursory nod to the true meaning of the Robin Hood mythology, unconsciously hacking a few ideas from the Robin of Sherwood series along the way. If the story is true concerning the need for producers of series one to step in and pay a ransom to retrieve the master copy, then they wasted a lot of money on a programme of bargain bin quality.
