Sunday Television Highlights for September 6, 2026
Viewers facing a crowded television landscape this Sunday, September 6, 2026, have a variety of new and returning content to track. The schedule includes a high-profile literary adaptation, multiple season finales, and ongoing mystery series. Major networks and streaming platforms are prioritizing established franchises alongside limited-run projects to capture the weekend audience.
The most notable arrival is the MGM+ limited series adaptation of A Tale of Two Cities. This four-part production brings Charles Dickens' classic to the screen with Mirren Mack as Lucie Manette, François Civil as Charles Darnay, and Kit Harington taking on the role of Sydney Carton. It premieres at 9:00 PM ET. Meanwhile, PBS is debuting the series Marble Hall Murders. In this mystery, Susan Ryeland, played by Lesley Manville, accepts a job completing an Atticus Pünd novel, only to become a primary suspect in a real-life death investigation involving Tim McMullan’s character.
Returning Shows and Season Finales
Several long-running programs hit their concluding episodes for the season tonight. At 1:00 PM ET, NBC concludes the fifth season of MLB Sunday Leadoff with a live matchup between the Atlanta Braves and the Philadelphia Phillies at Citizens Bank Park. Later in the evening at 9:00 PM ET, the Food Network broadcasts the finale of The Great Food Truck Race. The remaining two teams compete for a $50,000 prize at the Churchill Downs racetrack in Louisville, Kentucky, following a sales event at the Louisville Slugger Museum.
Returning series also dominate the prime-time hours. PBS launches the third season of The Marlow Murder Club at 8:00 PM ET. The plot centers on the sudden death of the town mayor during an official meeting, which prompts Judith, Becks, and Suzie to investigate allegations of blackmail and scandal. Simultaneously, the History Channel closes out the second season of Hazardous History With Henry Winkler. Winkler explores various dangerous activities from the 1970s, including homemade bicycle stunts and early amusement park machinery.
Mid-Season Drama and Genre Programming
Penultimate episodes drive much of the tension on cable television this Sunday. TNT’s The Librarians: The Next Chapter nears its conclusion as the team responds to a distress signal from Merlin. They must recover a magical artifact while contending with psychological manifestations of their own fears. AMC’s The Walking Dead: Dead City also reaches its penultimate installment, focusing on Maggie’s request for Negan to assist in the defense of her community as he nears a critical decision point.
Genre fans have additional options throughout the day. Peacock is streaming WWE: Sunday Night's Main Event at 8:00 PM ET, featuring a headline bout between Cody Rhodes and Randy Orton. Adult Swim continues its late-night lineup with President Curtis at 11:30 PM ET, a show that delves into the unusual premise of O'Doyle navigating a digital environment within Banks' computer brain. CBS remains anchored by Big Brother at 8:00 PM ET, where the latest Head of Household will determine the three houseguests nominated for eviction this week. These varied programs represent the current state of episodic television, where mystery, sports, and scripted dramas compete for viewer attention in a fragmented market.
