What’s On: Conan O’Brien heads to Mexico City for a prime-time comedy special on TBS

Conan Without Borders: Made in Mexico (10/9c, TBS): Exercising what might be best described as comedy diplomacy, the late-night host travels to Mexico City for a special broadcast, his sixth international visit in two years and perhaps his most timely, given the tension between the nations’ current leaders. Using an all-Mexican staff and crew, Conan O’Brien welcomes guests including former Mexican President Vincente Fox and Diego Luna (Rogue One). And if you’re missing Samantha Bee, don’t fret. She’ll return next Wednesday with new episodes of Full Frontal.

National Treasure (Hulu): Robbie Coltrane (Harry Potter, Cracker) stars in this grim four-part import from Britain’s Channel 4 as Paul Finchley, a beloved comedian whose career and reputation face ruin when he’s accused of multiple instances of sexual misconduct, including with underage victims. Julie Walters is also excellent as his wife, who has put up with Paul’s many extramarital affairs because he was never unfaithful “in an important way.” Now she, their troubled daughter (Andrea Riseborough), his former comedy partner and his public are having serious doubts.

The Goldbergs (8/7c, ABC): This season’s 1980s movie homage salutes The Karate Kid as Adam (Sean Giambrone) faces off against the Other Adam (Oliver Cooper), and who’s his Miyagi? His Uncle Marvin (Dan Fogler), so good luck with that.

Inside Wednesday TV: NBC doubles, then triples, down on its Chicago franchise to introduce the new Chicago Justice (10/9c) following a crossover of Chicago Fire (8/7c) and Chicago PD (9/8c) in a storyline involving a deadly arsonist. After this introduction, Justice moves to Sundays at 9/8c. … The final episode of PBS’s Nature miniseries Spy in the Wild invites viewers to “Meet the Spies” (8/7c, check local listings at pbs.org), going behind the scenes to see how the lifelike “spycam” creatures were developed, constructed and operated in regions around the world. … The second part of ABC’s When We Rise miniseries (9/8c) follows the gay activists in their fight against California’s discriminatory Proposition 6 in 1978, a victory that turns to tragedy when Harvey Milk is assassinated. The second hour is even more wrenching, as Cleve (Guy Pearce) and his brethren confront the confounding, then devastating, scourge of AIDS, inspiring him to create the AIDS Memorial Quilt.
