Moviegoers still mad for 'Madagascar 3'

Zoo animals remain hot at the box office. Singing stars and Adam Sandler are not.

Ben Stiller and his voice co-stars of "Madagascar 3: Europe's Most Wanted" held on to the No. 1 spot again, with $35.5 million for the animated sequel's second weekend in domestic theaters, The Associated Press reports.

Studio estimates Sunday put Ridley Scott's sci-fi adventure "Prometheus" at No. 2 again with $20.2 million. The star-studded musical "Rock of Ages," whose cast includes Tom Cruise, Catherine Zeta-Jones and Alec Baldwin, flopped at No. 3 with $15.1 million.

Sandler's "That's My Boy" bombed with $13 million, the worst showing for one of his broad comedies since the mid-1990s. "That's My Boy" came in at No. 5.
