What to Watch Tonight

Homeland and Affair Finales, Music Sing-Along and More

  • ABC
    The Sound of Music Sing-Along

    You do it anyway, but now ABC has made it easy as kinderleicht, with on-screen lyrics. (Be forewarned, there is no “Starbucks lovers” line in “My Favorite Things.”)

  • Fox
    Mulaney

    Time slot premiere: John’s resentment of Macaulay Calkin dampens his Christmas spirit. Meanwhile, Lou is worried when his rival (guest star Nick Kroll) announces a competing holiday special.

  • TNT
    The Librarians

    When the Serpent Brotherhood wants to kill Santa (nooo!), the Librarians must rescue the big guy and help him accomplish the true, secret purpose of Christmas. Bruce Campbell (Burn Notice) guest-stars.

  • CBS
    Undercover Boss

    Pittsburgh mayor Bill Peduto works as a refuse worker, a Housing Authority carpenter and a Forestry Division lumberjack, among other municipal duties.

  • Showtime
    Homeland

    Season 4 finale: Back in the States, Carrie and Saul investigate what she saw in Islamabad. (Already renewed.)

  • Food Network
    Top 10 Restaurants with Food Network Magazine

    From white tablecloth dinners to backyard BBQs, Bobby Flay hosts this countdown of the 10 must-eat meals of a lifetime — possibly including the banana-with-Skippy I had for breakfast.

  • CBS
    The Mentalist

    When the team investigates a murder linked to a counterfeit diamond operation, an illness forces Jane to direct his colleagues from the office. (Watch a sneak peek of “psychic” Teresa Lisbon.)

  • Showtime
    The Affair

    Season finale: Whitney’s disappearance spurs Helen to scrutinize Noah’s relationship with Alison. (Already renewed.)

  • E!
    House of DVF

    Season finale: Who will win?!?! (This is a competition series or something, right? I honestly do not know, and Vlada Gelman isn’t on IM right now.)

  • CBS
    CSI

    The investigation of the victim of an apparent hit-and-run leads the team into the world of aeronautics. Matt Letscher (Scandal, Castle) guest-stars, probably as a no-goodnik.
