“Robin Hood” opens a year late, with a Tomatometer rating of 44% and it is not expected to unseat “Iron Man 2” as #1 film over the weekend. Oh, and they disliked it at Cannes. Oh, and the budget is rumored to be $250 million and maybe even more. Would you believe this film began with one of the hottest screenplays in town? A screenplay that *was not about* Robin Hood?
