It looks like it will be Thor again, by default, on top of this weekend’s domestic box office. Though the summer movie season kicked off last weekend (two weeks ago if you count the giant debut of Fast Five), uncharacteristically low-profile debuts will help the God of Thunder retain his box office throne with a projected $32 million. Thor earned an estimated $9.1 million on Friday: down 65% from his May 6th debut. Bridesmaids, the female-skewing, R-rated comedy from producer Judd Apatow, came in second on Friday, bringing in an estimated $7.8 million from 2,918 locations and a projected $20 million for the weekend. The weekend’s second new release, Sony/Screen Gems’ Priest, placed fourth. The 3D adaptation of the sci-fi/horror graphic novel earned an estimated $5.6 million from 2,864 locations and is on track to earn $14 million over the weekend. That’s pretty low for a 3D fanboy pic, but it is actually more than the studio expected. Details tomorrow.
