Former 'Saturday Night Live' cast members Chris Parnell and Horatio Sanz have joined a new sitcom starring Jon Heder (of 'Napoleon Dynamite'), which is to start shooting at the end of the month for Comedy Central. The show, in which Heder plays a loser searching for some as-yet unidentified dream from his parents' couch ('Get A Life,' anyone?), already has writers/producers Will Ferrell, Adam McKay, and Chris Henchy aboard.

Parnell will play a "burned-out high school teacher," and Sanz as an ex-convict, both friends of Heder's character, whom he enlists to help with said unidentified dream, which somehow involves saving their home town of "Big Lake" (no word where that is). The show is set to premiere sometime this fall.

Hopefully, the sitcom won't prevent Parnell from appearing on '30 Rock' as Dr. Spaceman (pronounced "spuhcheman"), one of the show's more interesting cameos. And we'll get to see what Sanz looks like when he's not trying to keep himself from laughing.

Universal Pictures has just signed Brad Silberling to direct the big screen version of the '70s cult hit Land of the Lost. Silberling joins Will Ferrell on the project which is set to start shooting in March.

The original Saturday morning series told the story of explorer Rick Marshall who, while on a "routine expedition" with his children (for some reason) Will and Holly, fell through a fault in the Earth and ended up in a prehistoric world filled with dinosaurs, cavemen and evil lizard creatures known as sleestaks. Here's a little known fact, the "good" sleestak, Enik was played by NBA pro Bill Laimbeer.

People magazine is reporting that Brooke Shields is pregnant with a girl. That will be the second daughter for Shields and her television writer/producer husband Chris Henchy. Their first child is Rowan, age 2. Shields said, "I'm thrilled for my daughter to have a little friend. Two Tauruses, it's a huge trick being played on me."

I wonder if Tom Cruise is packing up a box of vitamins and sending a Bow-Flex to Brooke's house in anticipation of the birth.
