In this animated adventure -- based on Disney Channel's Emmy Award-winning comedy series "Phineas and Ferb" -- stepbrothers Phineas and Ferb go on their biggest journey yet, into another dimension! Povenmire and fellow producer Jeff 'Swampy' Marsh said, "We're thrilled about the music in 'Phineas and Ferb: Across the 2nd Dimension.'

Music plays a big role in the movie just like the series. We always try to pepper in songs whenever we can to hook the audience in and a song gets you emotionally a lot quicker sometimes than dialogue would. It¹s part of what makes things memorable about the show."
