TONIGHT'S MIGHT-SEES

Olympic trials, 7 p.m., NBC. We're near the finals now, forming the U.S. Olympic team. Tonight has swimming; tomorrow (6 p.m.) concludes the swimming and track-and-field trials.

"A Gunfighter's Pledge," 6 p.m., Hallmark. A fierce killer has escaped, as killers always seem to do in cowboy films. Now he's after the sheriff (Luke Perry) who killed his brother. Meanwhile, a rancher frets. His family has owned this land for generations, but now it's no longer part of Mexico. A businessman (C. Thomas Howell) wants to take it away.

These stories are related in a fairly solid movie. "Gunfighters Pledge" builds strong expectations, then stumbles. The shoot-out is poorly filmed; the ending is contrived. Still, it's a decent conclusion to Hallmark's cowboy marathon. Perry, from small-town Ohio, projects a quietly decent man, plunging into chaos.

OF NOTE

"The Magnificent Seven Ride" (1972), 7 a.m., Hallmark. The second day of the cowboy marathon begins with Lee Van Cleef in a rare hero's role.

"Confessions of a Teenage Drama Queen," 7 p.m., ABC. Lindsay Lohan plays a sophisticated, Manhattan teen suddenly moving to New Jersey. She grumbles, gripes, then obsesses about seeing a rock star.

"The Unit," 7 p.m., CBS. Grey is behind enemy lines with a female Israeli soldier.

"Eli Stone," 9 p.m., ABC. Eli has been demoted to the second spot, next to Maggie, in a case involving a doctor from his brother's hospital. Meanwhile, his former fiancee believes a concert by the real George Michael will end Eli's visions.

"Saturday Night Live," 10:29 p.m., NBC. Last week's rerun of the first "SNL" was a handy reminder of how the show has changed. "Weekend Update" was barely a blip and sketches were brief, making room for six songs, comedians and more. Now it's back to modern times. Jon Bon Jovi hosts, with Foo Fighters as musical guests.
