Daniel Craig is out, and Mark Ruffalo is in for Blindness. The movie is a high-concept pic from Constant Gardener director Fernando Meirelles, a sort of post-apocalyptic flick about a town where everyone suddenly goes blind. The only person who can see is Julianne Moore, who plays the wife of a doctor.

The doctor himself was to be played by Daniel Craig, but Variety says Mark Ruffalo now has the part. Ruffalo is a good actor, and should have no problem pretending to bump into walls and trip over curbs.

As for the movie, the concept sounds almost too clever. The tough thing will be keeping it from becoming a comedy. I’m sure they’ll amp up the tension with life and death situations to offset all the inevitable prat falls and unintentionally collisions. Julianne Moore will probably have kids to worry about and obsess over, she usually does. Worried mothers are her thing.
