Watching Jack Black Dance In 'Gulliver's Travels' Was One Of The 'Great Joys' Of Amanda Peet's Life

Back in the spring, we revealed that Jack Black will be "stirring things up" in the upcoming big-budget adaptation of the classic fable "Gulliver's Travels." Well, now we can add an additional trait to Black's character...dancer.

That's right, at the Sundance Film Festival "Gulliver's Travels" co-star Amanda Peet dished on her upcoming role as Black's editor (and love interest) who follows him after he doesn't return from an assignment. While clearly thrilled with playing "a giant," Peet was most excited about a little on-set song-and-dance.

"I saw Jack Black dancing in playback. He gets to sing and dance and that was one of the great joys of my life," Peet exclaimed to MTV News.

In the film, Peet and Black wind up as giants in a mysterious kingdom called Lilliputia filled with a rather diminutive population. Emily Blunt portrays a princess who experiences Black's shenanigans firsthand when he rolls into the palace, and Jason Segel will portray her love.

To achieve the massive size difference between Peet and Black and the citizens of Lilliputia, special models were constructed that gave the illusion of two giants in a strange land. Because of that, the filming was a new experience for Peet.

"It's crazy because we were crouching in a doll house type scenario," she said. "The set is filled with tiny things, miniature lights and just exquisite little details and stuff like that."

We'll see exactly how it all shakes out when "Gulliver's Travels" hits theater this December.
