Viewers will be able to spot a real government figure on the Feb. 6 episode of "24" (8 p.m. on Fox). Sen. John McCain, R-Ariz., a fan, was visiting the set in the fall when producers asked if he was interested in doing "a little Alfred Hitchcock star turn," executive producer Howard Gordon says. "We had a scene in which Audrey Raines (Kim Raver) needs to get a file folder from someone, and Sen. McCain delivered it."

McCain's nonspeaking cameo as an unidentified bureaucrat is so brief it seems like a "Where's Waldo?" moment, Gordon says. "If you blink, you'll miss it."

Before the scene, producers talked politics with McCain. "He was more interested in talking about scenes from '24,' " Gordon says. "He was able to cite chapter and verse from the seasons."

STARS SING YOU TO SLEEP

Scarlett Johansson, Ewan McGregor and Eric McCormack won't mind if you call their newest project a snooze. They're among 14 TV and movie stars lending voices to "Unexpected Dreams: Songs from the Stars," a CD of adult-aimed lullabies.

Due March 7 on Rhino, the disc features the crooning of screen stars, accompanied by the Los Angeles Philharmonic. Johansson warbles "Summertime," McGregor sings Sade's "The Sweetest Gift," McCormack does Elton John's "The Greatest Discovery."

Others contributing include Nia Vardalos, John Stamos, Jennifer Garner, Victor Garber, Julia Louis-Dreyfus, Lucy Lawless, John C. Reilly and Teri Hatcher. Proceeds will benefit Music Matters, the Philharmonic's fund for music education.
