TONIGHT'S MIGHT-SEES

"Wedding Crashers," 7 p.m., CBS. Big weddings seem to have endless food, fun and drink. So why not just slip in? That works fine for two guys — until one falls in love. This loose notion survives because of its cast. Vince Vaughn and Owen Wilson are fun; Rachel McAdams and Isla Fisher are charming. Also, Will Ferrell pops in uncredited.

"Accidental Friendship," 7 p.m., Hallmark Channel. In "Grey's Anatomy," Chandra Wilson is Dr. Bailey, crisp and forceful. Here, she plays the homeless Yvonne, clinging to her dogs and her dignity. There are lots of twists that would seem contrived, except this is based on a true story. There's good work from Ben Vereen (as Yvonne's friend) and Kathleen Munroe (as the cop who befriends her). Mostly, though, this is all Wilson in an Emmy-worthy performance.

OF NOTE

"The Bill Engvall Show," 6 p.m. and 6:30 p.m., TBS. This comedy returns briefly for two episodes, one of which has the kids shrugging about Christmas. That one is weak, with a record number of last-minute contrivances; the other episode is so-so, salvaged by one big sight gag to tie things together.

"Knight Rider," 7 p.m., NBC. In a quick rerun of Wednesday's episode, a criminal couple has political connections.

"The Wizard of Oz" (1939), 7 p.m., TBS; "The Godfather" (1972), 6 p.m., AMC. Here are two all-time great films.

"The Two Mr. Kissels," 7 p.m., Lifetime. Andrew Kissel and his brother Rob were envied, this film says; they were big-money guys with gorgeous wives. Both died young by murder or suicide. John Stamos stars, with Anson Mount, Robin Tunney and Gretchen Egolf.

"The Office," 8 p.m., NBC. In a rerun, Michael and Holly head to Nashua after getting major news from corporate.

"Ricky Gervais: Out of England," 8 p.m., HBO. The boyish charm of Ricky Gervais (creator of the original British series "The Office") can survive anything. Here, he manages to make jokes about AIDS, childhood cancer, Anne Frank and more. The result is erratic, but sometimes quite funny.

"Saturday Night Live," 8:30 p.m. and 10:29 p.m., NBC. First is a rerun, with details pending; then there's a new episode with Paul Rudd hosting and Beyoncé as the musical guest.
