'Treasure' finds gem in Mirren


Going from the mother of Prince Charles to the mother of Nicolas Cage, Oscar winner Helen Mirren has signed on for "National Treasure: Book of Secrets" and is being joined by Ed Harris, who is playing the antagonist in the Walt Disney Co. adventure.

The sequel reunites the cast of the 2004 hit film, which included Cage as treasure hunter Ben Gates and Jon Voight as his father, Diane Kruger, Justin Bartha and Harvey Keitel. Jon Turtletaub returns as director, and Jerry Bruckheimer is producing.

The story is set in motion when one of Cage's ancestors is implicated in the assassination of Abraham Lincoln, thrusting him into a globe-spanning adventure to clear his family name and find a missing treasure along the way.

CAA-repped Mirren, who last month won an Oscar for her portrayal of Queen Elizabeth II in "The Queen," is playing Cage's mom, Emily Appleton.

Harris, repped by CAA, is playing adversary Mitch Wilkinson.
