The reign of The Simpsons at the box office is likely to be shortlived as Matt Damon arrives with The Bourne Ultimatum this weekend. Most analysts are predicting that the thriller will wind up with about $60 million, while The Simpsons Movie will slip to second place with $35-40 million. (It crossed the $100-million mark on Thursday.) Three other films will be making their debut this weekend, including Disney's Underdog, which was not screened for critics ("a sure sign that the movie is a dog," remarked Kyle Smith in the New York Post). It's expected to place third with about $15 million. Expectations are not high for the other two, either. Paramount's Hot Rod and Lionsgate's Bratz: The two movies are each expected to earn less than $10 million.
