1) “American Masters,” 9 p.m., PBS. Here’s a joyous journey through Dick Van Dyke’s life. He turns 100 Saturday, so there’s a lot to cover. We see his elastic face and body in a nightclub act. His TV shows floundered until the brilliant “Dick Van Dyke Show” (shown here). Then came “Mary Poppins” and some serious turns, reflecting his struggle with alcoholism.
2) Taylor Swift. She shares Van Dyke’s birthday (albeit 64 years apart) and shares attention today. Disney+ debuts “The Eras Tour: The Final Show,” a concert film that included the “tortured poets” section she wrote during the tour; it also starts a six-part backstage documentary. ABC has the first two episodes at 8 and 8:30, then samples the film at 9.
3) “Wake Up Dead Man,” Netflix. The first two “Knives Out” films beautifully blended humor, smart mysteries and great characters. Here’s the third one, again with Daniel Craig as crimesolver. That wraps a streaming week that includes “Roofman” on Paramount+ and the season-openers of “Percy Jackson and the Olympians,” on Disney+ and Hulu.
4) “Sheriff Country” and “Boston Blue,” 8 and 10 p.m., CBS. Both shows were recently renewed for their second seasons. Tonight, the sheriff probes a shooting and has an awkward dinner with her stepsister. Lena, a Boston cop, probes a robbery and pushes the limits set by her mother, the district attorney.
5) ALSO: From 8-10 p.m., CW has the Hollywood Christmas Parade. At 8:30, NBC’s “Stumble” has Courteney take her rag-tag cheerleaders to the homecoming game at her old school … where her husband is football coach. And from 6 p.m. to 2 a.m., AMC has the fun “Elf” every two hours.
