Jesus Christ Superstar Live in Concert. Penn's own John Legend takes on the title role in an Easter night  performance of the 1970 rock opera from Andrew Lloyd Webber and Tim Rice. Sara Bareilles plays Mary Magdalene, Brandon Victor Dixon — who succeeded Philly's Leslie Odom Jr. as Aaron Burr in Broadway's Hamilton — is Judas, and rocker Alice Cooper is King Herod. 8 p.m. Sunday, NBC.

Counterpart. First-season finale of the parallel-universe thriller starring J.K. Simmons. 8 p.m. Sunday, Starz.

Brooklyn Nine-Nine. This Is Us star Sterling K. Brown guests as a murder suspect who's the subject of a nightlong interrogation. 8:30 p.m Sunday, Fox.

Masterpiece: The Child in Time. Benedict Cumberbatch (Sherlock) and Kelly Macdonald (Boardwalk Empire) star as the grieving parents in a moving adaptation of Ian McEwan's novel about a couple whose child disappears. 9 p.m. Sunday, WHYY12.

The Crossing. "From the network that brought you Lost" seems like a desperate pitch for this new time-travel series starring Steve Zahn (Treme) as small-town sheriff  in Oregon coping with an influx of refugees who've washed up on beaches, fleeing a conflict that's still far in the future. (Not quite as far in the future: the return  of The Good Doctor, which just ended its first season in this time slot.) 10 p.m. Monday, ABC.

King in the Wilderness. This film, which focuses on the final few years in the life of the Rev. Dr. Martin Luther King Jr., premiered this year at the Sundance Film Festival. 8 p.m. Monday, HBO. 

Legion. Of the shows I no longer remotely understand, this Marvel series from Noah Hawley (Fargo) is certainly the prettiest. Dan Stevens returns as David Haller, a  powerful mutant who'd long been considered schizophrenic. Wilmington's Aubrey Plaza plays David's friend Lenny, whose death in the first season's pilot doesn't seem to have hurt Plaza's screen time a bit.  10 p.m. Tuesday, FX.

The Last O.G. Tracy Morgan returns to series TV in a new comedy from Jordan Peele (Get Out) and John Carcieri in which he plays Tray, who emerges from prison after 15 years determined to be a shining light in his troubled Brooklyn neighborhood, only to find that the neighborhood's been gentrified. What's more, the love of his life, Shay (played by force of nature Tiffany Haddish), has moved on, big time. Couple or not, these two make an endearing pair. 10:30 p.m. Tuesday, TBS.
