By July, filming was delayed,[14] and playwright Paul Webb was hired to rewrite the script.[3] The film was moved to 2010.[15] The Sheriff of Nottingham's character was then merged with Robin.[16] Scott describes the identity of Robin, "In the context of the story he starts off as one thing, becomes the guise of another and then has to retire to the forest to resume his name Robin, so he was momentarily the Sheriff of Nottingham."[17] Helgeland returned to rewrite, adding an opening where Robin witnesses the Sheriff dying in battle, and takes over his identity.[18] Scott chose to begin filming in February 2009 in forests around London, having discovered many trees which had not been pollarded.[8] By February 2009, Scott revealed Nottingham had become his version of Robin Hood, as he had become dissatisfied with the idea of Robin starting as the Sheriff.[19]
