Jack Black: 'Year One' is historical document'

Jack Black has revealed his belief that new comedy Year One is a "historical document".

The Tropic Thunder star said that his upcoming biblical movie, which revolves around two hunter-gatherers deported from their village and summoned upon a voyage through the ancient world, pays homage to Monty Python's Life Of Brian.

"It's a big historical document, this movie. I'm in there as this primitive man," he told The Late Show With David Letterman.

Black joked: "We filmed it in primitive Shreveport, Louisiana. And in New Mexico, that looked biblical. We're like Neanderthal guys but we wander through biblical times and it's kind of a homage to Monty Python movies, like The Life Of Brian."

The actor stars in the film alongside Superbad's Michael Cera, who Black called the new Walter Matthau.

"Kyle Gass plays the eunuch brilliantly, born to do it. Michael Cera, he's 21 and so funny it's incredible. I say he's a young Walter Matthau. Less grumpy but just as brilliant," he added.

Year One is released to UK cinemas on June 2
