TONIGHT'S MUST-SEE

"Real Wedding Crashers," 7 p.m., and Miss Universe pageant, 8 p.m., NBC.

On the first Monday of the summer season, NBC has three hours without reruns. First is another "Crashers," with the bride and groom in on the joke. There's a monster-truck incident; also, an "escaped convict" shows up. Then women from 75 countries compete in Mexico City. Mario Lopez and Vanessa Minnillo host.

"Sunset Tan," 10:30 p.m., E.

In some ways, this is one of the emptiest reality shows ever. Others have people with skills in styling or fitness; here, we just see people give tans. Still, "Sunset Tan" has some jolting images. We see a grade-school kid, reluctantly getting a $1,200 tan for her school photo. We meet Holly and Molly, who are sort of like Paris and Nicole, only less intellectual. And we follow Erin, a preacher's kid from Oklahoma. Midway in her first office party, two of her bosses are naked.

OF NOTE

"On the Lot," 7 p.m., Fox. This reality show got off to a fun start last week, with 50 filmmakers pitching projects and shooting quickly. Tonight, the 18 survivors show their short films; viewers vote and three will be trimmed Tuesday.

"Two and a Half Men," 8 p.m., CBS. Brooke Shields plays a neighbor who's a lot like Alan. Charlie tries to hook them up.

"Ex-Wives Club," 8 p.m., ABC. We meet two survivors of bitter divorces. One says his wife cheated with his best friend; another says her husband called her a "bitch" on their honeymoon. Now they get an emotional makeover, guided by the exes of Donald Trump (Marla Maples), Sylvester Stallone (Angie Everhart) and Kevin Federline (Shar Jackson). Some people may find this uplifting; I found it to be an hour of wretched despair.

"Star Wars: The Legacy Revealed," 6 p.m., History Channel. "Star Wars" is 30 years old now and this documentary gathers steep praise on all sides. One former anchorman (Dan Rather) compares it to Beowulf and the Bible; another (Tom Brokaw) compares it to Robin Hood and Shakespeare. The current House speaker (Nancy Pelosi) calls it a classic; a former Speaker (Newt Gingrich) calls it "deeply American mythology."
