Disney/Pixar’s balloon adventure blockbuster “Up” won the best animated movie Oscar on Sunday, as the studio continued its dominance of cartoons at the Academy Awards.

That gives Pixar Animation Studios, which was bought by the Walt Disney Co in 2006, an industry-leading five Oscars for animation since that award was first handed out in 2002.

“Up” Director Pete Docter accepted the award on behalf of the studio and his animation team.

“Never did I dream that making a flipbook out of my third-grade math book would lead to this,” Docter said.

A flipbook is a crude animation that children often make, with drawings on a series of pieces of paper that seem to move as the pages flip.

“Up” came out last May in 3-D and made more than $700 million at worldwide box offices.

The film is about a curmudgeonly old man named Carl, who is voiced by Ed Asner, and a young boy named Russell who fly off in a house tied to helium balloons.
