Matt Damon's latest movie proved that it was a Bourne leader at the box office over the weekend. In fact, The Bourne Ultimatum led all movies ever released in August as it drew an estimated $70 million and helped lift the overall box office 35 percent over the same weekend a year ago. The original Bourne movie, The Bourne Identity, registered $27.1 million in 2002. It was followed in 2004 with The Bourne Supremacy, which took in $52.5 million. In its second week, 20th Century Fox's The Simpsons Movie -- the box-office winner last weekend -- plunged 65 percent to $25.6 million. Nevertheless, its strong midweek grosses brought its domestic total to $128.5 million over 10 days. It has earned almost the same amount overseas. Arriving in third place was Disney's Underdog, which was not screened for critics (see below). The film grossed an estimated $12 million -- about what Disney had expected. Two other newcomers fell flat. The comedy Hot Rod starring former Saturday Night Live costar Andy Samberg earned only $5 million to wind up in ninth place, while the "tween" film Bratz went blatz with $4.3 million to finish tenth.
