Best Bets on TV Tonight

"Big Brother" (8 p.m., CBS) is not only watching, he's living with you and ready to vote against you. The fifth installment of this reality series follows a group of strangers living together. No ordinary group rental, this home is totally wired, as cameras and microphones record everyone's every move, 24 hours a day. Over a span of three months, the roommates will vote one another out of the house, each hoping to be the last one home and the winner of the $500,000 prize.
Plenty of big names in "The Misfits" (8 p.m., TCM) with Clark Gable and Marilyn Monroe, both in their last film; director John Huston; writer Arthur Miller. This is one of those movies that got a lukewarm welcome on arrival (in 1961) but is gaining a better reputation with the passage of time.
The race is on, again. CBS' Emmy-winning reality show "The Amazing Race 5" (9:30 p.m., CBS) returns with 11 couples in an international competition for a $1 million prize and solid bragging rights. The first leg of the trip stretches from a pier in Santa Monica, Calif., to Uruguay, with tension and gamesmanship aplenty from the airport on.
In "War Feels Like War," (10 p.m., PBS) filmmaker Esteban Uyarra chronicles the experiences of journalists who refused to be "embedded" with American forces to cover the war in Iraq. These "unilaterals" took great risks to provide a different perspective.
