The Showtime television network says it is preparing a new documentary on former Vice President Dick Cheney.

Showtime said Thursday that filmmaker R.J. Cutler, who made "The War Room" about Bill Clinton's presidential campaign in 1992, will make the film. No date was set for airing.

Cutler called Cheney, who was George W. Bush's vice president, "perhaps the single most influential non-president in the nation's political history." He promised a balanced and multi-dimensional look at Cheney.

Last weekend, Cutler placed ads in the Casper Star-Tribune newspaper asking residents if they had any footage or still pictures of Cheney. The former vice president lived in Wyoming as a teen and attended the University of Wyoming. He represented Wyoming in Congress from 1979 to 1989.

"Maybe somebody has a home video somewhere that we haven't heard about that we'd just like to see," said Ryan Gallagher, as associate producer at Actual Reality Pictures, Cutler's production company.

Showtime said it has begun an effort to produce high-end profiles. Its other project is about rap mogul Suge Knight.
