THE MIGHTY BOOSH Stream on Hulu and Amazon. Before Noel Fielding was serving up baking banter and an impressive array of kitschy shirts on “The Great British Baking Show,” he was one half of the outlandish comedy duo behind The Mighty Boosh. Fielding and his counterpart Julian Barratt created a colorful roster of characters and original skits and songs that became the basis for this BBC Three television series named after the troupe. The show, which aired for three seasons in the early 2000s, follows the misadventures of Vince Noir (Fielding) and Howard Moon (Barratt) as they investigate mutant science experiments at a zoo’s secret lab, save the world from a demonic little old lady and explore another planet for the Fountain of Youth. Along the way, they stumble across new friends and foes, like a beast made of sandpaper, a terrifying green-skinned cockney man with a mint over his eye and a Baileys-drinking, lovelorn merman known as Old Gregg.

MEETING GORBACHEV 6 p.m. on History. Over the course of three in-depth interviews, Werner Herzog sat with Mikhail S. Gorbachev to talk about the Russian leader’s diplomacy that helped bring an end to the Cold War. The dialogue between the German filmmaker and the former politician (now 88 years old) serves as this documentary’s backbone, in which Herzog examines Gorbachev’s legacy. In his New York Times review of the film, Ben Kenigsberg wrote that Herzog “seems less in his element as an interviewer than he is when parsing historical footage,” but still manages to shape “the film into a study in how world events often come down to quirks of character and circumstance.”

THE DNA OF MURDER WITH PAUL HOLES 7 p.m. on Oxygen. After spending more than two decades trying to catch the Golden State Killer, Paul Holes, an investigator with the Contra Costa County district attorney’s office, finally got a break in the case when he thought to combine DNA collected at the crime scenes with genealogy websites. The innovative scheme, which involved creating an undercover profile on GEDmatch under a pseudonym, led to the arrest of Joseph James DeAngelo. Holes has since retired, but he’s gone on to use his expertise to help with existing cold cases as a co-host on the podcast “The Murder Squad,” and now with his own TV show. On “The DNA of Murder,” Holes gives true crime fans a behind-the-scenes look at how he approaches cases, aiding law enforcement agencies with unsolved crimes. On the series premiere, he’ll look into a bludgeoning murder at an Iowa Holiday Inn from 1980.
