Will Ferrell returns to theaters this week in 'Land of the Lost,' which is based on the classic television series created by Sid and Marty Krofft.

Ferrell stars as has-been scientist Dr. Rick Marshall, who gets sent back through 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.

Traveling alongside him for the adventure are crack-smart research assistant Holly (Anna Friel) and a redneck survivalist (Danny McBride) named Will. Chased by a T-Rex and stalked by painfully slow reptiles known as Sleestaks, Marshall, Will and Holly must rely on their only ally -- a primate called Chaka (Jorma Taccone) to navigate them out of the hybrid dimension. Escape from this routine expedition gone awry and they're heroes. Get stuck, and they'll be permanent refugees.

Out on DVD is a vintage classic, 'Eddie Murphy's Delirious - 25th Anniversary.' Taped live and in concert at Constitution Hall in Washington, D.C.' in August of 1983, the concert film captures Murphy's wild and outrageous stand-up comedy act. Stories of hot childhood days and the ice cream man are intermixed with classic vocal parodies of top American entertainers. Murphy, then 22, was live and red hot, uncensored and uncut!

As teenagers get ready to graduate from high school this month, prom night is that last shindig many can look forward to. In the documentary 'The World's Best Prom,' we get a glimpse into the world of prom-goers.

Once a year, prom mania grips the entire population of Racine, Wis. The city's extravagant celebration begins with a rowdy parade in which students compete for the most outrageous form of transportation, driving fire engines, 18-wheelers, even riding elephant-back through the city streets. Prom-goers from seven city high schools converge on one citywide prom to make red-carpet entrances and are bombarded by the flash of cameras and screams from bleachers filled to capacity. Meanwhile, in sports bars and living rooms across the city, residents keep their eyes glued to the live television coverage of the spectacular event. If the Academy Awards moved to the heartland, this is what it would resemble.
