The original “Star Wars Holiday Special,” which aired exactly once 42 years ago today, was a famous failure. A new attempt, made entirely with plastic toys, “The LEGO Star Wars Holiday Special” (Disney+, streaming) builds on the mythology, buoyed by the knowledge that it’s supposed to be funny. 

The one new broadcast network show this season comes from David E. Kelly, who years ago created “The Practice” and “Ally McBeal” and has lately had success on cable adapting big glossy dramas like “Big Little Lies” and “The Undoing.” Now back on network TV, he adapts “Big Sky” (ABC, 10 p.m.), from a book series by C.J. Box. It’s about a pair of sisters kidnapped by a truck driver on a remote Montana highway and a trio of detectives who go looking for them. The cast includes Ryan Phillippe, Kylie Bunbury, Katheryn Winnick and John Carroll Lynch.  

Cheese rolling, frog jumping, chili eating and dog dancing are among the oddball competitions profiled on the new series “We Are the Champions” ((Netflix, streaming) from Rainn Wilson. 

It’s no secret that the nation is politically split; “Frontline” (PBS, 10 p.m., check local listings) looks further into the partisan divide in a report called “American Voices: A Nation in Turmoil.”

Barack Obama is interviewed on “The Oprah Conversation” (AppleTV, streaming) as part of the book tour for his memoir, “The Promised Land,” out today. The program is available for free through Dec. 1.

“NCIS” (CBS, 8 p.m.) begins its 18t season going after a drug ring. 

Starting its third season is “FBI” (CBS, 9 p.m.), investigating a mass shooting at a media company., followed by a second season of “FBI: Most Wanted” (CBS, 10 p.m.), whose first season came in January.
