Universal has released a full length trailer for Land of the Lost on Subwayfreshbuzz.com. It’s basically an extended version of the teaser that played during the Super Bowl. We get to see more of the fantastical land in the alternative universe Dr. Rick Marshall (Will Ferrell), Will Stanton (Danny McBride), and Holly (Anna Friel) get transported to: a realm ruled by dinosaurs, monkey-men called Pakuni, and the murderous Sleestak.

Director Brad Silberling (Lemony Snicket’s ‘A Series of Unfortunate Events’) says he fought to keep the human shape of the Sleestak from Sid & Marty Krofft’s original production, and not give into the urge to render them as spindly computerized beings. In the ’70s TV show, they were guys in lime-green pajamas — and looked it. The Sleestak are much sleeker now, but the film is largely a comedy, so the guy-in-a-suit look has its charms, Silberling says:

“There is a sense of humor that I loved from the original show that can only come from an actor trying to negotiate the suit. If it became CG, they’d be too perfect. For the Sleestak to remain in people’s memories, it tells you that it was about who was in the suit.”

The movie is set to release in theaters June 5, 2009.
