Their new romantic comedy, Forces of Nature, swept aside all comers at the megaplex this weekend with an estimated $13.9 million in receipts.
It's the second straight box-office No. 1 for Bullock: Her Practical Magic debuted in the top slot with $13.1 mil back in October. (Affleck, on the other hand, wasn't so lucky with his last, 200 Cigarettes, which barely registered on the charts.)
Coming in second: the Robert De Niro-Billy Crystal mafia laugher Analyze This, which continued strong in its third week with about $11.9 million.
Most Industry types figured this would be a slow movie weekend, thanks to the Oscars Sunday night. And with the exception of Forces of Nature and Analyze This, the prognosticators were right.
The weekend's supposed other big gun, Clint Eastwood's True Crime, tanked, finishing a distant third with a measly $5.3 million.
The other debuts also underperformed. The animated The King and I opened in sixth with $4.2 million; the black comedy cannibal flick Ravenous didn't even make the Top 10, raking in only $950,000.
