The Paley Center Salutes This Is Us (10/9c, NBC): A week before the breakout hit tearjerker returns for a long-awaited third season, this special recaps the first two eventful and emotional years for the Pearson family and looks behind the camera at the production process. Interviews with actors, writers and producers analyze what these beloved characters have been through and where they’re going.

Life Below Zero (9/8c, National Geographic Channel): Winner of a cinematography Emmy this year, the grueling survivalist docu-series returns, introducing a rugged new regular: Ricko DeWilde, a native Quoi Can Athabascan Indian raised in the Alaskan bush, who practices native traditions while living off the grid amid harsh Arctic conditions.

'More than 1,000 people' helped in the making of this series says producer Orla Doherty.

The Hunt for the Trump Tapes with Tom Arnold (10:30/9:30c, Viceland): Described as a “comedy/investigation hybrid,” this hysterical (in all the wrong ways) series finds the overwrought comedian, and former Roseanne spouse, turned “citizen journalist” and crusader on a quest to dig up any and all of the elusive recordings rumored to show the president in a bad light. (The tweets aren’t enough?) Arnold seems to be serious about his mission, but it’s hard to take this mad clown seriously.
