Well, don't we all feel a little silly. Transformers: Revenge of the Fallen, the movie that received the most hysterically negative reviews of 2009 opened to by far the year's biggest numbers -- $201 million since Wednesday, according to estimates. That's just a couple million shy of the first-five-days-of-release record set by The Dark Knight, though that movie opened on a Thursday. (It's tough to truly compare opening weekends of mega-blockbusters these days, since God knows on what day of the week they all hit theaters.) I hope everyone is looking forward to Transformers 3, where Autobots will discover fart jokes.

The only movie to dare take on Revenge of the Fallen in wide release, was the Nick Cassavetes weepie My Sister's Keeper, which opened to a respectable $12 million -- almost as strong as Cassavetes' The Notebook, though unlikely to be carried to an $80 million cume by good word-of-mouth. Year Onetook a big tumble, falling off 70% its middling opening; I guess Michael Cera and Jack Black aren't quite the automatic draw that battling cyborgs are. And The Hangover continues to ride a wave of audience goodwill; it will likely have reached $200 million by this time next weekend.

As for your weekly Up v. Finding Nemo update -- it's still neck-in-neck, with Nemo ahead by about $3 million after five weeks of release. If this weekend's heftier drop-off for Up is any indication, it may be starting to lose a little steam, which would mean that Nemo would get to hold on to the Pixar crown.
