Los Angeles ? First, she sells out a nationwide concert tour. Now Miley Cyrus and pop-star alter-ego Hannah Montana are selling out movie theaters in such record-breaking style that the film’s run has been extended.

“Hannah Montana & Miley Cyrus: Best of Both Worlds Concert,” the 3-D film chronicling her recent tour, was the biggest debut ever over Super Bowl weekend, pulling in $29 million, according to studio estimates Sunday.

Distributor Disney planned to have the movie out for only a week but now has decided to keep it in theaters until it runs its course.

The concert film – featuring 15-year-old Cyrus both as herself backstage and as her Disney Channel character, pop sensation Hannah – filled the void for fans unable to catch one of the live shows on the Hannah Montana 54-date tour.

The digital 3-D technology also gave fans the illusion of practically being at a live show, said Mark Zoradi, president of Disney’s motion-picture group.

“The screaming level was unbelievable. It almost plays like a concert. At the end of a song, you have audiences clapping like you do at a concert,” Zoradi said. “Parents who weren’t able to get concert tickets, now they were able to take their kids and satisfy that demand, and kids were in a way able to be up close and personal, with the best seats in the house.”

“Desperate Housewives” co-star Eva Longoria Parker delivered a dud with her first top-billed movie, “Over Her Dead Body,” which opened with a weak $4.6 million to finish at No. 11. Distributed by New Line, the movie stars Longoria Parker as a dead woman whose ghost tries to break up a romance between her fiance (Paul Rudd) and his new girlfriend.

Grosses for “Hannah Montana” were boosted by higher admission prices many theaters charged because of the 3-D format. Tickets for “Hannah Montana” ran as high as $15, roughly 50 percent more than the top price for other movies.

The success of “Hannah Montana” showcased the commercial prospects for an upcoming wave of 3-D releases, both new movies such as this summer’s adaptation of Jules Verne’s “Journey to the Center of the Earth” and rereleases such as the first two “Toy Story” films in 3-D versions.

Digital projection allows sharper and more realistic images than old-fashioned film 3-D, a 1950s fad revived only occasionally over the decades. Now, many big studio films come out in 3-D versions.
