The Jonas Brothers' performance at the weekend boxoffice proved not so extra-dimensional.

Disney's "Jonas Brothers: The 3-D Concert" rung up an estimated $12.7 million to open in second place among domestic rankings. The haul was roughly half what many had expected for the pic based on growing appeal of 3-D projection and anticipated support among preteen fans.

The soft bow allowed Tyler Perry's "Madea Goes to Jail" from Lionsgate to repeat at No. 1 despite a big 60% drop from opening grosses. The urban comedy registered $16.5 million on the session for a 10-day tally of $64.8 million representing Perry's best-ever theatrical cume.

Like Hilary Duff and Miley Cyrus before them, the Jonas Brothers have grown from early exposure on the Disney Channel to broader public acclaim. Their hitting the big screen with a 3-D concert pic followed a similar move by Cyrus in February 2008.

Disney opened Cyrus' 3-D concert film, "Hannah Montana/Miley Cyrus: Best of Both Worlds," to $31.1 million in what initially was billed as a one-week-only release. "Best of Both Worlds" eventually was extended and rung up $65.3 million overall domestically.

So in a notable distinction from "Concert," the bow for "Best of Both Worlds" was enhanced by fans' belief that they had to catch the Cyrus pic over its first weekend. "Concert" is set for a multiweek run, so before the pic's release, studio execs cautioned against expecting a Joneses bow of Cyrus proportions.

"I'm as happy as can be," Disney distribution president Chuck Viane insisted Sunday. "When you're looking at almost $10,000 per auditorium, that's doing really well. And it's the N. 2 concert opening of all time."

"Best of Both Worlds" played in just 687 theaters because of limited 3-D availability at the time; "Concert" played in 1,271 venues. "Concert" audiences skewed 85% female, with 65% of patrons age 17 or under.
