3-D dance documentary 'Pina' gets an Oscar nod

LONDON (AP) — Wim Wenders wanted to make a dance movie for 20 years, but had to wait for technology to catch up with his imagination.

The German director says he needed the power of 3-D to make "Pina," a tribute to the late choreographer Pina Bausch that was nominated Tuesday for a best documentary Academy Award.

Wenders said 3-D "has a glorious future, especially in the documentary field, because it is the best way to bring an audience into the world of the film."

The other contenders for best feature documentary are Afghan war film "Hell and Back Again"; eco-saga "If a Tree Falls: A Story of the Earth Liberation Front"; high school football documentary "Undefeated"; and "Paradise Lost 3: Purgatory," about three U.S. teenagers jailed for a notorious triple slaying.
