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.
