I just had a nine hour shift this past Saturday, and I was the only one cleaning theaters. I'll tell you, having a job makes you have some newfound respect for various things.
And to bring things back on topic, I think Thor should have a fairly strong hold next weekend. Its main competition for its own market is Priest, which I don't see being extremely successful, although taking some of the 3D market will have a noticeable impact. Bridesmaids is a largely different market that skews a little older, so all things considered, I'd be surprised if Thor had the dreaded 60% drop. Especially given that it didn't open with monumental numbers. But you know, we'll see.
