Ellen Gray's weekend TV picks: 'Last Kingdom,' 'Walking Dead' and more

* THE LAST KINGDOM. 10 p.m. Saturday, BBC America.

"Vikings" fan alert: This series, adapted from Bernard Cornwell's "The Saxon Stories" novels, might help tide you over until Season 4 arrives on the History Channel next year. Alexander Dreymon (pictured) stars as Uhtred, a Saxon noble's son who's captured and raised by invading Danes. If he's ever to reclaim his birthright, he'll need to navigate the tricky territory between the two cultures.

* PROPHET'S PREY. 9 p.m.

Saturday, Showtime.

Filmmaker Amy Berg, whose 2006 doc, "Deliver Us From Evil," chronicled the case of a pedophile priest, turns her lens on the polygamous Fundamentalist Church of Latter Day Saints, its leader Warren Jeffs and the abuses that finally sent him to prison. Writer Jon Krakauer ("Under the Banner of Heaven") figures prominently here, too.

* THE WALKING DEAD. 9 p.m. Sunday, AMC.

Season 6 of AMC's zombie-filled mega-hit opens with a 90-minute premiere that's as much about humans threatening each other as it is about their staggering enemies. I may not have the fortitude to go the distance with Rick (Andrew Lincoln) and his contentious band of survivors, but I can't deny that the performances remain the show's strength.

* SUPERSOUL SUNDAY. 7 p.m. Sunday, OWN.

Oprah Winfrey interviews Nobel Peace Prize winner Malala Yousafzai, the young Pakistani who survived being shot by the Taliban to become a crusader for girls' education.
