That crashing sound you'll hear emanating from cineplexes this weekend will be the sound of comic-book superheroes smashing box-office records.
Actually, the smashing started last weekend, when Marvel's The Avengers opened in 39 territories around the world, scooping up a cool $178 million in three days. And with legions of fans having already bought advance tickets in the U.S., it's a pretty sure bet the box-office bonanza will continue as the film opens in more than 4,000 North American theaters.
The perjury case against baseball star Roger Clemens appeared to be falling apart on Wednesday. Key witness Andy Pettitte, who had previously said Clemens told him he had used human growth hormone, said he was only "50-50" on whether he heard Clemens correctly. And the judge is thinking about striking the Pettitte testimony. Nina Totenberg talks to Robert Siegel.
