TONIGHT'S MUST-SEE

"Saturday Night Live," 8 p.m. and 10:29 p.m., NBC. On Super Bowl eve, NBC does everything it can to draw a crowd. First, there's a collection of old sketches, called "Saturday Night Live Sports Extra." This could be a mixed blessing. When putting athletes in sketches, "SNL" has had some good moments (Peyton Manning, Lebron James) and some awful ones (Michael Phelps, Michael Jordan). All four of those stars will be included here, plus Tom Brady, Charles Barkley, Derek Jeter, Wayne Grezky and more. Then comes a new episode, bringing back the show's best host, Steve Martin. These days, some fans only know Martin as the guy who does bland movie remakes and sequels. (His second "Pink Panther" movie arrives next Friday.) He has been brilliant, however, as host and at stand-up; his music guest tonight is Jason Mraz.

TONIGHT'S MIGHT-SEE

"The Note II: Taking a Chance on Love," 7 p.m., Hallmark. Last season's "The Note" (which reruns at 5 p.m.) was an OK film about an advice columnist (Genie Francis), tracing a letter someone wrote before a fatal plane crash. Now comes the sequel, as she sorts out complications with her boyfriend (Ted McGinley), her daughter and a stranger with an intriguing story. All of this is well-meaning, but flawed. Douglas Barr, who directed both "Note" films, also wrote the script this time; he has too many characters speaking in the same psycho-pop voice.

OF NOTE

"Heroes," 8 a.m. to 9 p.m., G4 (Oceanic Digital Channel 437). The second half of the "Heroes" season starts Monday. Leading into that, here's a 13-hour marathon; it starts with the season opener, when we learned who shot Nathan.

"The Chronicles of Narnia: The Lion, The Witch and The Wardrobe" (2005), 7:30 p.m., ABC Family. Some families, not caught up in Super Bowl obsession, can try this fantasy epic; it also airs at 5 p.m. Sunday.

"Anchorman: The Legend of Ron Burgundy" (2004), 7 p.m., ABC. There are lots of funny moments, with Will Ferrell as a lightheaded TV anchor. The only problem is that it doesn't know when to stop, throwing silly moments in with the good ones.

"Crusoe" season-finale, 7 p.m., NBC. By now, Crusoe realizes Blackthorn (Sam Neill) is his enemy. As his men reach the island, Crusoe and Friday need a plan.

"Super Bowl's Greatest Commercials," 7 p.m., CBS. Here's another show designed for Super Bowl Eve. Jim Nantz and Daisy Fuentes introduce what are called the 10 best commercials to debut during the game.

"NCIS," 7 p.m., CBS. In a change, CBS inserts this rerun. While tracking a serial killer, Ziva finds her life in danger.

"Life on Mars," 9 p.m., ABC. After a long break, this interesting show — with a nowadays cop stunned to find himself working in the 1970s — returned Wednesday. Here's a rerun of that episode. Two squads — Hunt's and Nunzio's — compete to solve a case involving the Russian mafia; a 9-year-old may be the key witness.
