TONIGHT'S MUST-SEE

"Keith Barry: Extraordinary," 7 p.m., CBS. Keith Barry is a young Irish magician, still in his 20s, who has caught on quickly. He had a series in Ireland that reportedly went to 28 countries. Then his "Brainwashed" special was a ratings success on MTV. Now he has a deal that includes corporate partners CBS and MTV. In this network special, Barry does some broad tricks — inducing memory loss, risking $1 million on a card trick, driving a car blindfolded. He also does some close-up magic with celebrities watching. Showing up in this hour are Jessica Simpson, Wilmer Valderrama, Elijah Woods, Matthew McConaughey, Eve, Nicollette Sheridan, Vivica A. Fox and more.

OF NOTE

"Legally Blonde 2: Red White & Blonde" (2003), 7 p.m., Fox. The original movie was surprising fun with Reese Witherspoon as an air-headed sorority girl who conquers Harvard Law School.

Two members of Sugarland, Jennifer Nettles and Kristian Bush, will perform.

"Conviction," 9 p.m., NBC. Steele has trouble on a rape case because the plaintiff's father is belligerent. Potter bungles an easy case, Desmond deals with an odd fortune-teller and Cabot throws a fancy engagement party.
