Scott Grimes, Kevin Durand and Alan Doyle have been cast as the group of adventurers in Universal and Imagine's untitled Robin Hood movie, starring Russell Crowe and being directed by Ridley Scott. The feature is being billed as a retelling of the origins of the key characters of the Robin Hood legend. Cate Blanchett is on board as Maid Marian in the project, written by Brian Helgeland (“A Knight's Tale”). Grimes, who appears on NBC's “ER” and does voice work for Fox's “American Dad,” has been cast in the role of Will Scarlet, a skilled swordsman and Hood's nephew. Durand is playing Little John, Hood's right-hand man. He is best known in the legends for fighting a duel with Robin Hood using quarterstaves while trying to cross a river. Durand, who appears as the Blob in “X-Men Origins: Wolverine,” is best known for his work on ABC's “Lost,” where he played a mercenary named Martin Keamy. Doyle is playing Alan a Dayle, a roving minstrel who in lore enlisted help when his love was being forced to marry another man. Doyle is the lead singer of Great Big Sea, a Canadian folk-rock band known for its sea shanties.
