Emily VanCamp (“Everwood”) stars in the network Hallmark presentation “Beyond the Blackboard” (8 p.m., CBS). VanCamp portrays an overwhelmed rookie teacher assigned to teach a group of homeless children in a makeshift classroom in an underfunded shelter. Look for Timothy Busfield (“thirtysomething”) as an indifferent bureaucrat. VanCamp’s “Everwood” co-star Treat Williams also stars.

Hallmark movies generally extol a fantasy view of rural life, so it’s always interesting when they take place in a grim urban setting. Except such grimness usually gives way to sunshine with the application of a little paint and the sunshine disposition of a plucky girl.

• “Treme” (9 p.m., HBO) opens its second season a year after Hurricane Katrina, as national attention and concern for New Orleans begins to fade and outside developers begin bargain hunting in distressed districts. This beautifully shot and well-acted series requires a little patience from viewers willing to marinate in the Crescent City atmosphere.

In other HBO news, the premium network has already renewed “Game of Thrones” (8 p.m.) for a second season. The ultra-violent and utterly humorless head-scratcher apparently has a cult audience. Tonight, Daenerys learns to please her grim groom.

• Speaking of grooms, TLC devotes much of the coming week to Friday’s much-ballyhooed royal wedding. It’s a perfect match for TLC, a network seemingly obsessed with dresses, cakes and cupcakes. Just short of having Jon Gosselin interred in Westminster Abbey, they’ve pulled out all the stops with such programming as “Charles & Di: Once Upon a Time” (7 p.m.); “Untold Stories of a Royal Bridesmaid” (8 p.m.); and “Royally Astounding: 30 Defining Days of Monarchy” (9 p.m.). The last covers the Monarchy over the past 30 years.

• Folks who didn’t catch “The Kennedys” the first time can catch it when it runs on Reelz (8 p.m.) every night this week.

Tonight’s other highlights

• Scheduled on “60 Minutes” (6 p.m., CBS): a rare look at life in a monastery in Mt. Athos, Greece, a place largely unchanged over the centuries.

• Homer saves the day and the world in the 2007 feature-length “Simpsons Movie” (7 p.m., Fox).

• A best-of “South Park” (8 p.m. to 12 a.m., Comedy Central) marathon unspools.

• The three-part revival of “Upstairs Downstairs” concludes on “Masterpiece Mystery” (8 p.m., PBS, check local listings).

• Justin keeps a secret on “Brothers and Sisters” (9 p.m., ABC).

• Rosie’s teacher offers a new clue on “The Killing” (9 p.m., AMC).

• Lucrezia strays on “The Borgias” (9 p.m., Showtime).

Cult choice

TCM celebrates Easter ’70s-style with two period musicals, “Jesus Christ Superstar” (7 p.m.) and “Godspell” (9 p.m.), both from 1973. Look for Victor Garber (“Titanic”) in “Godspell.”
