Sacha Baron Cohen's Bruno tops the weekend box office grosses, according to BoxOfficeGuru.com. The lewd, crude comedy sold an estimated $30.4 million in tickets, better than Cohen's Borat, but there's a catch before he begins celebrating.

Borat opened to $26.4 million in 2006, on nearly one-third fewer screens (and with slightly lower ticket prices). Cohen's breakout hit had legs, though, expanding to more theaters and winding up with $128.5 million in domestic revenues.

Bruno has already opened as wide as it will. Given the usual weekly dropoff in ticket prices -- 35 percent lower is still considered a successful encore -- it'll be tough for Bruno to match its predecessor's total.

Bruno didn't exactly dominate the weekend race. Ice Age: Dawn of the Dinosaurs placed second with $28.5 million. Beating a second-week movie by less than $2 million in the summertime takes a bit of glitter off Bruno's victory. And with the Harry Potter flick opening Wednesday, it won't become a winning streak like Transformers: Revenge of the Fallen.
