TONIGHT'S MUST-SEE

"Saturday Night Live," 10:29 p.m., NBC. This wraps up a four-week stretch of new episodes. Next come prime-time half-hours, on the last three Thursdays before the election. So far, "SNL" has had great political moments, with mixed success at anything else. The first week was awful; the next two have been fairly good. Tonight, Anne Hathaway ("Brokeback Mountain," "The Devil Wears Prada") hosts, with music from The Killers.

OF NOTE:

Facing a football-baseball avalanche, some channels counter with love and a musical: At 4:30 p.m., TNT has "Titanic" (1997), a warm drama tucked inside an epic. At 8, ABC Family has the richly emotional "The Notebook" (2004), plus the E channel has the zesty musical "Chicago" (2002).

Baseball, noon, TBS. It's a doubleheader, with the third games of two best-of-five National League playoff rounds. First, the Philadelphia Phillies visit the Milwaukee Brewers; then the Chicago Cubs visit the Los Angeles Dodgers.

Football, 2 p.m., ABC. Oregon goes up against Southern Cal at home in a big football day.

"Knight Rider," 7 p.m., NBC. A rerun night starts with this hour: Some drag-racers double as weapons runners. They're fast, so Mike must chase them in KITT. Sarah joins the mission, something her dad isn't happy about.

"Chuck," 8 p.m., NBC. The season opened Monday with this bright, jaunty hour. A new computer is almost ready, making Chuck sort of unneeded. He figures that's a good thing and he can finally date his beautiful spy colleague; there may be a catch, though.

"EliteXC Saturday Night Fights," 8 p.m., CBS. Try to remember that CBS was once called the Tiffany network. This features martial-arts fights.

"Law & Order: Special Victims Unit," 9 p.m., NBC. When a teen confesses to lusting for his young stepbrother, detectives begin investigating predators and a Web site.
