n a series so much like “Downton Abbey” you might start looking for familiar characters, the new “Belgravia” (Epix, 9 p.m.) is from the same author, Julian Fellowes, and luxuriates in the same lavish costumers, sets and music.
The always good Tasmin Grieg stars as a woman with a secret that threatens to upend a social corner of mid-19th century London. Philip Glenister, Harriet Walter and Alice Eve also star. It only runs six episodes and has a more pronounced storyline than its predecessor (though the vast downstairs staff seems unnecessary).
It runs opposite the original home of “Downton,” where on the second episode of “World of Fire” (PBS, 9 p.m., check local listings), World War II approaches its second month.
The always splendid Merritt Weaver stars opposite Domhnall Gleason in the new series “Run” (HBO, 10:35 p.m.), playing former college flames who once agreed to meet later in life once a signal is given. They do drop everything and meet on a cross country train, though it seems the premise may run out of gas before the locomotive.
“Run” is partly from Phoebe Waller-Bridge of “Fleabag” fame, who helped create another hit that returns tonight, “Killing Eve” (BBC America, AMC, 9 p.m.). Its cat and mouse story seems like it needn’t have lasted more than a season, yet the interplay between Sandra Oh and Jodie Comer was so popular, here it is for a third season, where Comer’s over-the-top assassin thinks her pursuer Oh is dead. Unlike other shows that were delayed by the pandemic, this one was pushed up a few weeks to satisfy fans sheltering in place. And Harriet Walter, also in “Belgravia,” is featured this season as a former Russian trainer.
Also returning tonight: season four of Issa Rae’s stylish city comedy “Insecure” (HBO, 10 p.m.) in which she begins to plan for a big neighborhood block party.
The anticipated new episode of “Tiger King” (Netflix, streaming) is only an aftershow reunion chat, featuring interviews with John Reinke, Joshua Dial, John Finlay, Saff, Erik Cowie, Rick Kirkman, and Jeff and Lauren Lowe. As well done as some of its reality programming is, from “The Circle” to “Love is Blind,” its after shows are fairly underwhelming.
The detective from the series “The Missing” returns to star in a new series, “Baptiste” (PBS, 10 p.m., check local listings). Tchéky Karyo revives his role as detective Julien Baptiste. Tom Hollander and Jessica Raine are also in the six-part mystery, set in Amsterdam.
More than 100 comedians are interviewed giving advice and personal experience in the documentary “This Is Stand-Up” (Comedy Central, 10 p.m.).
Easter entertainment comes with the replay of the 2018 “Jesus Chris Superstar Live in Concert” (NBC, 7 .m.) with performances by John Legend, Sara Bareilles and Alice Cooper.
Lucille delivers a baby in an elevator on “Call the Midwife” (PBS, 8 p.m., check local listings).
Dolly Parton gets her due in a two hour “Biography” (A&E, 8 p.m.).
And “Willie Nelson: American Outlaw” (A&E, 10 p.m.) salutes another country star in a tribute concert featuring George Strait, Chris Stapleton, Dave Matthews, Emmylou Harris, Vice Gill, Eric Church, Jimmy Buffett, Sheryl Crow and Norah Jones.
On “God Friended Me” (CBS, 8 p.m.), Miles and Rakesh try to avoid a bounty hunter.
Sebastian is injured while trying to prevent a kidnapping on “NCIS: New Orleans” (CBS, 10 p.m.).
The new series “ID Breaking Now” (Investigation Discovery, 10 p.m.) looks at very recent cases in the news. The first, on Harvey Weinstein, includes interviews with some of his victims.
The utter lack of sports for a month leads to this: A H.O.R.S.E. Challenge (ESPN, 7 p.m.), in which NBA stars match shots from their respective home courts. Specifically, Trae Young vs. Chauncey Billups, Tamika Catchings vs. Mike Conley Jr., Zach LaVine vs. Paul Pierce and Chris Paul vs. Allie Quigley.
The voice of Wayne Williams is heard at a community meeting there almost nobody believes he was the killer on “Atlanta’s Missing and Murdered: The Lost Children” (HBO, 8 p.m.).
“Outlander” (Starz, 8 p.m.) returns with a new episode, in the aftermath of the Battle of Adamance Creek.
No one admits to anything on “Homeland” (Showtime, 9 p.m.).
There’s more background on the lives of the Top 21 before viewers vote on “American Idol” (ABC, 8 p.m.).
An earthquake shakes the jungle on “Naked and Afraid” (Discovery, 8 p.m.).
On “Black Monday” (Showtime, 10 p.m.), a new client presents a problem for Dawn. (They’ve stopped showing two new episodes each Sunday in order to slow down the storytelling and stretch things out during the pandemic).
The home version of “This Week Tonight with Jon Oliver” (HBO, 11:10 p.m.) is gaining in confidence.
“The Rookie” (ABC, 10 p.m.) finds his first informant back on the streets with drugs.
But there’s only a windstorm on “When Calls the Heart” (Hallmark, 8 p.m.).
“Buddy vs. Duff” (Food, 9 p.m.) square off over an aquarium cake.
A trip to Key West is in the offing on “Family Karma” (Bravo, 9 p.m.).
An arsonist targets an FBI safe ouse on “NCIS: Los Angeles” (CBS, 9 p.m.).
“Westworld” (HBO, 9 p.m.) went officially off the rails last week.
Easter movies on Turner Classic Movies begin early with “The Silver Chalice” (5 a.m.) and continue with “Barabbas” (7:30 a.m.), “Ben-Hur” (midnight), “The Greatest Story Ever Told” (4 p.m.), “Easter Parade” (8 p.m.) and “King of Kings” (10 p.m.).
They are followed by by the talkie “The Jazz Singer” (1 a.m.) and the Japanese imports “Lone Wolf and Cub: Baby Cart to Hades” (2:45 a.m.) and “Lone Wolf and Cub: Baby Cart in Peril” (4:15 a.m.).
