ENCHANTED KINGDOM (2014) 9 p.m. on BBC America. Whether he’s acting in “The Wire,” “Luther” or “The Office,” or performing as a D.J. at some of the world’s largest music festivals, Idris Elba can command an audience. But in this immersive documentary, the sweeping visuals take center stage, and Elba simply lends his voice as a narrative guide. “Enchanted Kingdom” takes viewers across Africa, examining plant and animal life in some of the continent’s harshest and most complex environments. Like “Planet Earth,” the film features state-of-the-art camera techniques that capture close encounters with nature, from active volcanoes to the depths of the ocean.

LAVELL CRAWFORD: NEW LOOK SAME FUNNY! 10:35 p.m. on Showtime. You might recognize Lavell Crawford from “Breaking Bad,” where he played Saul Goodman’s bodyguard, Huell Babineaux, or from his stint on “It’s Always Sunny in Philadelphia” as Landslide, a catchphrase-loving comic. But Crawford has been performing stand-up for years, first on “ComicView” on BET in the 1990s, and later as a contestant on “Last Comic Standing” on NBC. In his latest comedy special, he touches on his recent 120-pound weight loss, former President Barack Obama’s first term and his view of the police in 2019.
