Final Approach (8 p.m. Saturday, Hallmark Channel) -- Dean Cain plays a cashiered FBI agent. He's a passenger on an airliner. It gets hijacked! Whoooa, didn't see that coming. But wait . . . that flight attendant . . . doesn't she look familiar? Yikes, it's Sunny Mabrey, from Snakes On A Plane! Oh, man, don't open the overhead bin!

Lord of the Ants (8 p.m. Tuesday, WPBT-PBS 2) -- Speaking of crazed anthropomorphism, this episode of the PBS science series Nova is a profile of Harvard biologist E.O. Wilson, legendary for his fascination by and affection for ants. (Clearly he didn't watch enough of those big-bug sci-fi flicks in the 1950s.) Wilson is notorious in scientific circles for arguing that all behavior in all animals is governed by biology and that free will is a myth. In this documentary, you can watch him plunge his hand into a bed of fire ants while calmly observing that each sting feels like ''the touch of a hot needle,'' which certainly suggests that free will on occasion may not be such a great concept.

Indiana Jones and the Kingdom of the Crystal Skull (PG-13) -- Is Harrison Ford too old to don Indy's fedora one more time? Not according to director Steven Spielberg and producer George Lucas, who finally came up with a script to everyone's liking after more than a decade of false starts. Set in 1957, the latest Indiana Jones adventure takes place at the height of the Cold War, with Soviet agents (led by Cate Blanchett) taking over for Nazis. Karen Allen returns as Marion, and Shia LaBeouf joins the fun as a young adventurer who may or may not be Indy's son. Also, there is the titular Crystal Skull, which may or may not have something to do with aliens. Opens Thursday.
