M. Night Shyamalan‘s Lady in the Water did 4% less business on Saturday than it did on Friday. That’s due to word-of-mouth, of course. It might have dropped even more if it hadn’t been for the rain that hit the northeast (and especially the New York City area) on Saturday. Lady is going to end up with about $18,165,000…the weakest Shyamalan showing since he became “big.” Kevin Smith‘s Clerks 2 suffered a big Friday-to-Saturday drop also. It went from a 7.21 take of $3,967,000 to a haul of about $3,214,000 on 7.22. Sorry to be the bearer but that’s a 20% dropoff…bad. It may not even make $10 million by this evening. Ivan Reitman‘s My Super Ex-Girlfriend will finish seventh with $8.5 million…another tank.
