“National Treasure 2: Book of Secrets”

Nicolas Cage takes the current president hostage in his quest to clear an ancestor in the assassination of another. Cage scored his latest blockbuster hit with this “National Treasure” follow-up, reprising his role as a historian and treasure-hunter who traipses around the world sorting out clues that will help exonerate one of his forebears of conspiracy in the death of Abraham Lincoln. And of course, along the way, he stumbles on another hidden trove of vast riches, accompanied by his mom and dad (Helen Mirren and Jon Voight), his estranged girlfriend (Diane Kruger) and an adversary (Ed Harris) with his own dark family history. A two-disc DVD set and the Blu-ray high-definition release pile on the extras, including deleted and extended scenes featuring introductions from director Jon Turteltaub, who is joined by Voight for commentary on the full movie. Behind-the-scenes segments feature cast and crew including producer Jerry Bruckheimer on visual effects, stunts and the history behind artifacts and legends in the story. The Blu-ray release has two extra deleted scenes plus a quiz on the fact and fiction in the movie. Also debuting on Blu-ray is the first “National Treasure,” with commentary from Turteltaub and a new featurette. DVD set, $29.99; “National Treasure” and “National Treasure 2” Blu-ray releases, $34.99 each. (Disney)

“The Delirious Fictions of William Klein”

American photographer, documentary filmmaker and satirist Klein offers up three wild tales he created in the 1960s and ’70s, set in his adopted country, France. “Who Are You, Polly Maggoo?” tears apart the haughtiness and artificiality of the fashion world as it follows the adventures of a Brooklyn model in snooty Paris. “Mr. Freedom” features an arrogantly uncompromising U.S. superhero who comes to Paris to fight the Communist menace. “The Model Couple” is centered on a man and woman chosen for their dreary commonness as subjects who are put under surveillance for a series of strange, intrusive tests to better society. DVD set, $44.95. (Eclipse)
