Nottingham would've been the single most original Robin Hood movie in history. The original script (written by Ethan Reiff and Cyrus Voris) so excited studios when it turned up in 2007 that it became the subject of a fierce bidding war (Universal wound up paying freaking $1.5 million for it). It was a totally different take on the story -- the Sheriff of Nottingham is the main character and protagonist. "Stuff" gets real once the sheriff investigates a string of grisly murders in the area. The sheriff then pursues "a jerkish" Robin Hood (Russell Crowe) for the crimes only to find out that Robin, while a "jerk", was actually being framed.
The film was to climax with an epic siege of the city of Nottingham between Prince John and King Richard, all while the Sheriff tries to discover the identity of the real killer using 12th century detective techniques (Reiff is a history buff and researched how actual killings in that era were investigated).
Then, director Ridley Scott came on board and said, "What is this "crap"? We're making a Robin Hood movie! Get all that standard Robin Hood stuff back in there. That's what everybody wants to see." The movie was renamed Robin Hood and lots more scenes with people shooting bows and arrows were added. A few rewrites later, very little of the original screenplay remained. Today, Nottingham is a cautionary tale for every young, aspiring screenwriter out there. It doesn't matter what you write: the director and the star will decide what makes it onto the screen.
