A group of danger-courting daredevils and a martial-arts master have kicked the Rock out of the #1 spot.

"Jackass: Number Two" bowed at the top of the box-office top 10 this weekend, earning more than $28.1 million, according to early estimates. The flick bested the opening weekend of "Jackass," which debuted with $22.8 million in 2002. "Number Two" features the usual suspects — including Johnny Knoxville, Bam Margera, Chris Pontius and Ryan Dunn — taking on stunts that threaten to kill, maim or at least comically injure the daring "Jackass" crew (see " 'Jackass' Guys Taunt Sharks, Yaks; Visit Hospital Often In Gross-Out Fest 'Number Two' ").

Another risk-taking performer debuted high on the box-office top 10, as "Jet Li's Fearless" opened at #2 with more than $10.5 million. The film centers on Huo Yuanjia (played by Jet Li), a real-life — and self-taught — martial-arts master who became one of the greatest fighters in China despite his intense personal drama.

These fearless daredevils knocked a group of fledgling footballers from their #1 post. "Gridiron Gang," a fact-based drama starring Dwayne "the Rock" Johnson as a probation officer who inspires a group of juvenile offenders to excel on the football field (see " 'Gridiron Gang' Story Squeezed Tears From The Rock"), slipped from #1 to #3, earning $9.7 million its second weekend in theaters.

The action film "Flyboys" bowed at #4 after earning more than $6 million during its debut weekend. The film centers on a group of young Americans who volunteered to fight with the French during World War I to become the world's first combat pilots.

"Everyone's Hero," the animated family flick about a young boy who embarks on a cross-country trek to help Babe Ruth and the Yankees with the World Series, dropped from #3 to #5 with more than $4.7 million.

Under the weight of three new releases, "The Black Dahlia" — which debuted last week at #2 — dropped four notches to #6 with more than $4.4 million. The film was inspired by the notorious unsolved mystery surrounding the brutal murder of 22-year-old actress Elizabeth Short, who was found dead in Hollywood in 1947.

Rounding out the box-office top 10 are "All the King's Men," which bowed at #7 with $3.8 million; "The Covenant," which dropped from #4 to #8 with $3.3 million; "The Illusionist," which fell from #7 to #9 with more than $3.2 million; and "Little Miss Sunshine," which slipped from #8 to #10 with more than $2.8 million.

Overall, ticket sales were down from the corresponding weekend last year.
