Gone, but not forgotten

In 2016, the world lost a staggering number of beloved entertainers, particularly from the music world, but TCM is here to remind us that recently deceased character actors also deserve a moment — if not the entire evening. The “in memoriam” tribute kicks off with George Kennedy “egging” on Paul Newman in “Cool Hand Luke” and continues with films featuring Gloria DeHaven, Alan Rickman, Patty Duke, Marni Nixon and Nancy Reagan.

Night, mother

Left the family’s holiday festivities on a sour note? Watch a repeat of “Nothing Left Unsaid: Gloria Vanderbilt and Anderson Cooper,” a mother-and-child reunion to cherish, with the CNN anchor gently guiding his famous mother through her painful past with some serious bonding moments along the way. Then phone home. Life is too short.

Hip to be square

With the first season of a surprisingly brazen “Divorce” behind us, it’s time to re-appreciate Sarah Jessica Parker in the show in which she first shined. No, I’m not talking about “Sex and the City.” Dial back the nostalgia machine for a four-hour run of early-1980s “Square Pegs” in which the actress managed (barely) to get through high school without the aid of Cosmopolitans.
