I SHOULDN’T BE ALIVE
8 p.m. Friday, March 10
The Discovery Channel (Comcast Ch. 53)
I saw a bumper sticker the other day: “Jesus was my co-pilot,” it said. “But we crashed in the mountains and I had to eat him.” Like a lot of humor, that joke is based on dark doings: a plane crash in the Andes that led to cannibalism. History is full of events like that, which brings us to the new series, “I Shouldn’t Be Alive.” Each week, through re-creations and interviews, the Discovery Channel seeks out those who survived peril by the skin of their teeth. This week, an Australian backpacker must make a heart-wrenching decision when his friend is trapped under a boulder in a rain-swollen creek bed.
HOW WILLIAM SHATNER CHANGED THE WORLD
7 p.m. Sunday, March 12
The History Channel (Comcast Ch. 70)
Though the original “Star Trek” series and its subsequent spin-offs might seem like the most disposable TV dreck imaginable to the uninitiated, there’s one thing most folks haven’t thought of: Geeks love “Star Trek.” And, as geeks are the folks with the brainpower to invent things, Star Trek’s bells-and-whistles vision of the future has often served to guide the path some of our best and brightest minds took in their lifelong endeavors. Here, in conversations with scientists and deep thinkers, we see the influence Captain Kirk and friends have had on cellular communications, medical technology, computers and even space travel.
JOHNNY CASH: ANTHOLOGY
8:30 p.m. Tuesday, March 14
AETN (Comcast Ch. 3, Broadcast Ch. 2)
n What with a new bio-pic about his life getting rave reviews and a slew of new fans because of it, Johnny Cash is surely closing in on the title of World’s Most Famous Arkansan, second only — maybe — to that politician from Hope who made his way through Little Rock a couple years back. You know: Mike Huckabee. But seriously, folks, the least you can say about Johnny Cash was that he was a certified genius, possibly even the first practitioner of “alternative country.” Still, Cash never forgot where he came from. Here, PBS puts together some of the best of Cash’s concert footage, with interviews with family and friends in between. Included: performances of “Ring of Fire,” “Big River,” “Folsom Prison Blues,” and “I Walk the Line.”
