In "Land of the Lost", now available on DVD & Blu-Ray Disc, Will Ferrell stars as has-been scientist Dr. Rick Marshall, a man sucked into a time portal and transported back in time. Way back. Now, Marshall has no weapons, few skills and questionable smarts to survive in an alternate universe full of marauding dinosaurs and fantastic creatures from beyond our world--a place of spectacular sights and super-scaled comedy. Based on the classic television series created by Sid & Marty Krofft, ''Land of the Lost'' is directed by Brad Silberling and produced by Jimmy Miller and Sid & Marty Krofft. Moviehole caught up with Brad Silberling to chat up the film.

How did you get Leonard Nimoy as the voice of The Zarn?

BRAD: It was a real simple idea. We knew The Zarn would only have two scenes. In the original series he had this great voice, so I thought we should get someone great, so if you don't know who it is it will have an impact but if you do it will be great because it fits into the science fiction thing. He was great. The first day I brought him into record. He was not tremendously familiar with the original show and you begin to sit and explain these science fiction explanations of The Zarn and then you think, "Oh my god. How ridiculous! Look who I'm talking to?" Probably every week on Star Trek they had these synopses that were the weirdest things.

Do you think it would go far off from the original concept? BRAD: I think if you were going to do a faithful recreation, it would have happened twenty years ago and I think there is a reason it didn't happen. The show was a product of Saturday morning television. It was very earnest. It was like a Swiss family Robinson show with greater imagination and none of us were interested in doing that.  We were inspired more by what was really psychedelic about the show.  And like all good comedy if you took a set of characters making all the wrong choices it would be really funny, This to us was a really enjoyable way to create something we haven't seen - action adventure with a comic premise.

Were Sid and Marty open to the changes?

BRAD: I think they were very happy very quickly. They knew they had someone directing who was a real fan of the show.

There are some interesting music choices in the movie. How were they made?

BRAD: It was a nice small working tribe. Chris Henchy and Dennis McNicholas were the two writers who set about reworking the script. As a filmmaker I recognized we were going to have this Maltese Falcon - this quest for the tachyon amplifier and as simple as the quest was, out of the vastness of the land of the lost, we won't be able to know where it is unless we can actually see it. You won't know if you are close. I thought we needed an audio cue that would be really funny if it was a contemporary song that Marshall can be embarrassed about every time. So we all pitched. Would it be a bad power rock ballad? But we loved the idea it would be an old Broadway show and we thought A Chorus Line was genius then I got excited because I wanted Cha-Ka to sing the final aria.

Any thoughts of a sequel?

BRAD: I say it truly without being coy. We had a fantastic time - we will wait and see. There have been no concrete ideas yet but we had a great time.
