Going into the final rounds of the holiday battle at the box office today (Monday), Ben Stiller's Night at the Museum was pounding Sylvester Stallone's Rocky Balboa. The Stiller comedy has earned an estimated $30.8 million through Sunday while the Stallone boxing drama had earned $22.1 million. (That figure also included receipts for Wednesday and Thursday; Friday-through-Sunday receipts were put at $12.5 million). Last weekend's winner, The Pursuit of Happyness, starring Will Smith, also put up a good fight, earning $15 million over the weekend,to bring its 10-day total to $53.3 million. Two other newcomers did only so-so-to-poor business: Universal's CIA drama The Good Shepherd raked in $10 million to place fourth, while Warner Bros.' football flick We Are Marshall managed only to bring in $6.6 million, placing sixth. But Mel Gibson's Apocalypto suffered its own apocalypse over the weekend, plunging off the top-ten list after debuting in first place two weeks ago. The movie earned just $3 million over the weekend.

1. Night at the Museum, $30.8 million; 2. The Pursuit of Happyness, $15 million; 3. ROCKY BALBOA, $12.5 million; 4. The Good Shepherd, $10 million; 5. Charlotte's Web, $8 million; 6.
