The Cannes rumor mill is whirring at full speed again today as the trades pick up whispers that the Julianne Moore/Mark Ruffalo drama Blindness is likely to occupy the opening-night slot. The Toronto Star is saying it's a done deal, but it's not official, and we're not so sure; with barely two weeks remaining before the May 14th opener, word over the Defamer transom suggests that Blindness is bad enough to make festival programmers wait — and make distributor Miramax stall — before committing the plum spot to a stinker.
