Jonas Brothers [ tickets ]' fans in Hollywood got a big surprise last night (2/26) when the teen sensations showed up to the midnight screening of their new movie, "Jonas Brothers: The 3D Concert Experience."

The pop trio arrived at the El Capitan Theatre and performed three songs before the film's start. Though it might have appeared impromptu, the rockers have planned what they're calling a surprise theater invasion, visiting movie theaters in cities around the country during the film's opening weekend.

The 3D Disney rockumentary is sure to be a box-office hit. Director Bruce Hendricks, the mastermind behind the mega-successful "Hannah Montana/Miley Cyrus: Best of Both Worlds Concert," helmed the Jonas Brothers' version. The film focuses on their "Burning Up" concert tour with guest performances by chart-topping country songstress Taylor Swift and Disney Channel heroine Demi Lovato.

In a press release, Nick Jonas said, "We love giving back to fans, because they give so much to us, and I think this is a great way to show how much we appreciate them."

The group will travel the nation with the help of NetJet, a fractional-ownership, private-aviation company, and fans can keep up with the brothers through videos available only on Verizon Wireless' V Cast-enabled phones.
