A convalescing Ridley Scott will miss Wednesday's opening-night world premiere of Robin Hood at the Cannes Film Festival. "I recently underwent knee replacement surgery, and my recovery has been slower than I'd hoped," the director said today in a statement. "Truly, doctor's orders are the only thing that could keep me from being there." Scott added his blessing of Russell Crowe, Cate Blanchett, producer Brian Grazer and the rest of the Hood-ies in attendance, then reurned to developing his next nine films. [THR]
