American Idol

American Idol
9/8c Fox
It's lights, camera and action for our fab four, who were the reel deal last night by performing songs of the cinema, with actor Jamie Foxx guiding them along with his mentorship. But Idol viewers are the final critic, and now Crystal Bowersox, Lee DeWyze, Casey James and Michael Lynche anxiously await America's thumbs-up or thumbs-down in this results installment. Alas, one will end up on the cutting-room floor. Providing the soundtrack are performers Bon Jovi and Daughtry, fronted by Season 5's Chris Daughtry. — Dean Maurer

America's Next Top Model
8/7c CW
The final four models (Alexandra, Angelea, Krista, Raina) are whittled down to two during the first part of tonight's two-hour 14th-season finale in New Zealand. The last two ladies standing then shoot a CoverGirl commercial before taking to the runway in a circus-inspired show for designer Anna Sui. Krista and Angelea look to be the top models to beat, but who knows what Tyra is thinking? — Tim Holland

New Adventures of Old Christine
8/7c CBS
Eric McCormack returns as Christine's fiancée, Max, for the fifth-season finale, in which Christine convinces Matthew and Barb to throw her and Max a "surprise" engagement party. Why? So she can better get to know Max's friends. Unfortunately, Christine begins to feel intellectually inferior at the big event, and it leads her to make a bold decision. Could this be the end of Christine and Max? — Tim Holland

Mercy
9/8c NBC
The hospital ensemble drama centering on the ups and downs of a trio of disparate nurses ends its inaugural season. In this final nurse verse, caregiver Veronica springs into action to help two youngsters who are trapped in an empty building. Meanwhile, materializing as one of Sonia's patients is a psychic (Aida Turturro) who offers a prediction about Sonia; a desperate Dr. Briggs (James Van Der Beek) works to pay off his debt to mobsters; and Sands introspectively considers accepting a new job — in Afghanistan. Jennifer Esposito also guest-stars. — Dean Maurer

American Masters
9/8c PBS
The Doors: When You're Strange is a fan's dream rockumentary, leaving the story we know so well to Johnny Depp's deft narration while featuring only footage — much of it previously unseen — from the band's formation in 1965 to singer Jim Morrison's death in 1971. Along the way, we see Morrison engaging in a figurative slow-motion self-immolation that occasionally erupts into uncontrollable flames, most notably at the infamous 1969 Miami concert when he supposedly exposed himself. — Jeff Gemmill

Top Chef Masters
10/9c Bravo
The champions round resumes with the remaining culinary masters tooning up with the cast and crew from the enduring cartoon sitcom The Simpsons. Voice virtuoso Hank Azaria, creator-writer Matt Groening and writer Matt Selman join the judges' table for a challenge inspired by the show's characters. It could get interesting, especially considering Homer's diet (donuts and beer). Afterward, the chefs whip up surf-and-turf dishes by using proteins that are exotic (read: gross and unappealing). — Dean Maurer

Music by Prudence
8/7c HBO2
For many casual filmgoers, the first exposure to this 2009 Oscar-winning documentary short was probably when the film's estranged producer, Elinor Burkett, awkwardly interrupted director Roger Ross Williams' acceptance speech. Fortunately, that memory likely won't be a lasting one after viewing the remarkable story of Prudence Mabhena, a 21-year-old Zimbabwe woman who overcame a severe disability and cultural prejudices to become an accomplished singer-songwriter and accepted member of society. — Joe Friedrich
