Weekend Box Office (05/08/11): Thor grosses $65.7m, Fast Five crashes, and other debuts perform well.

It's a $65.7 million weekend for Thor (review), giving the Marvel adventure pic a solid 2.6x weekend multiplier. It's kinda scary how accurately we can now predict opening weekend grosses just based on the midnight number, but the math once again worked (Thor did 5% of its weekend gross via Thursday midnight sneaks, per usual). Anyway, Marvel was successful at keeping expectations low, saying that anything over $60 million would be a win. And it more-or-less is. The film played heavily 3D, which meant higher ticket prices and the like. I heard plenty of anecdotal stories about moviegoers unable to find a convenient 2D location, which may be part of a depressing trend as the 'summer of 3D' unfolds. But the film had a solid weekend multiplier (if you discount the $3.25 million worth of midnight sneaks, the film's Friday and Saturday figures were pretty even) and decent word of mouth. It earned a B+ from Cinemascore, with an A from those under 18.
