"Children of Beslan" (noon, HBO): This documentary marks the one-year anniversary of the terrorist
"Children of Beslan" (noon, HBO): This documentary marks the one-year anniversary of the terrorist siege at a Russian elementary school that ended with more than 350 deaths. The chilling story is revisited from the point of view of the children, ages 6 through 12, who suffered through it.
"Armageddon" (8 p.m., ABC): Plenty of action here, as the title suggests. When Earth is threatened by a Texas-size asteroid, the only hope seems to be if Bruce Willis and Billy Bob Thornton can figure out how to blow it up with a nuclear bomb. Also starring in this 1998 movie are Ben Affleck, Liv Tyler and Steve Buscemi.
"AFI's 100 Years ... 100 Movie Quotes" (8 p.m., Bravo): We've lost count of how many of these countdown shows the American Film Institute has put together, but this one might be worth a second look even if you know the "winner." One quibble: The line, "Houston, we've got a problem" comes from real life, so "Apollo 13" hardly deserves credit for it. Pierce Brosnan is the host.
Jules Verne's Mysterious Island (8 p.m., Hallmark): A well-known cast and plenty of special effects are among the attractions of this new version of the story of a journey to an uncharted land. Patrick Stewart stars as Captain Nemo, along with Kyle MacLachlan, Gabrielle Anwar and Omar Gooding. The film was shot on location in Thailand -- just before the tsunami struck in December.
"Shall We Dance?" (9 p.m., Starz): A burned-out lawyer (Richard Gere) finds new meaning to life when he starts taking dance lessons because he's attracted to one of the instructors (Jennifer Lopez). But how long can he hide his new obsession from his wife (Susan Sarandon)? Also starring are Lisa Ann Walter and Stanley Tucci.
