While their new movie "Jonas Brothers: The 3D Concert Experience" is reeling at theaters across U.S., Jonas Brothers continue to promote it with TV appearances. The movie premieres on Friday, February 27 and on the next day, the three brothers, Nick Jonas, Kevin Jonas and Joe Jonas, visit "Good Morning America" for another boost of support.

During the taping, the brothers are seen in preparation for their theater invasion which has been announced earlier. "Well, we are doing some amazing things," Kevin explained. "We have joined partners with Marquis Jet and NetJets. Without them, we couldn't do this. But we are flying around the country and actually stopping in and saying hi to fans who are actually going to see the movie this weekend and you know, saying hello and just surprising them."

However, they told co-host Kate Snow that they couldn't reveal which theater they were heading to. It turned out later that day, they popped out at Palisades Mall in Nyack, N.Y. They had also been in theaters in Atlanta and Charlotte, N.C. and would visit several others.

Despite the heavy promotion, Jonas Brothers cannot lift up the movie to land at the top of North American Box Office chart. The movie grossed only 12.7 million dollars throughout the 3-day weekend, 2.3 million dollars shy of what the producers have expected. "Madea Goes to Jail" stands firm on its first place, grossing 16.5 million dollars.
