According to The Hollwyood Reporter, 20th Century Fox's Big Momma's House 2 more than pulled its weight at the boxoffice this weekend, as the Martin Lawrence starrer easily snagged the top spot with an estimated $28 million. It was January's second-biggest opening after Star Wars: Special Edition ($35.9 million) and was Lawrence's second-highest opening behind Sony Pictures' Bad Boys II ($46.5 million).

The comedy sequel, helmed by John Whitesell, opened better than anticipated as most observers had the film in the high teens- to low-$20 million range. The original Big Momma's House bowed during the summer of 2000 with $25.7 million. Universal Pictures' Nanny McPhee worked some magic this weekend as the Emma Thompson starrer landed in the second spot with a higher-than-expected debut of an estimated $14.1 million from 1,995 theaters. Produced by Working Title and directed by Kirk Jones from a screenplay by Thompson, the PG-rated family comedy had the second-highest per-theater average of the top 12 films.

Steven Spielberg's Munich opened internationally in 30 markets this weekend for an estimated $15 million from 3,000 screens, enough to snatch the overall No. 1 boxoffice ranking from Buena Vista International's The Chronicles of Narnia: The Lion, the Witch & the Wardrobe, which had dominated for five consecutive weeks.

Fox International rolled out Big Momma's House 2 day-and-date with the Martin Lawrence comedy's domestic opening, chalking up an estimated $5.4 million from 1,026 screens in five markets, notably Australia ($1.6 million from 191 screens) and Mexico ($1.6 million from 445 screens). Global weekend opening tally is an estimated $33.4 million.

The United International Pictures release of Spielberg's drama about tracking down terrorists who murdered Israeli athletes at the 1972 Olympics had a notable opening in France, yielding an estimated $2.5 million at 437 locations. In the U.K., Munich bowed to $2.15 million at 350 screens; in Germany, $1.68 million from 394 screens; in Spain, $1.6 million from 22 screens; and in Australia, $1.4 million from 172 locations. Munich finished in the No. 1 spot in Israel with $151,000 from 30 screens.
