The poster comes from Empire Magazine, while the website was launched by Universal Pictures, the studio behind the film.  The website found here, has some pretty cool stuff on it.  There is of course the trailer, as well as cast and crew info, synopsis, photo gallery, a pretty good video looking at the story, and some history behind the popular legend.  Definitely worth checking out if you are looking forward to the film.

The Ridley Scott directed film stars Russell Crowe, Cate Blanchett, William Hurt, Matther Macfadyen, Mark Strong, Oscar Isaac, Lea Seydoux, Scott Grimes, Kevin Durand, Alan Doyle, Danny Huston and Max von Sydow.  Robin Hood hits theaters on May 14th and looks like it could be on the same level as Gladiator, also from Scott and Crowe.

Props to ComingSoon.net for the find.
