The not-so-fresh prince

A Will Smith action movie used to be a shoo-in for blockbuster status. The fact that his latest, “Bright,” is debuting Friday on Netflix is a sign of both his waning box-office clout and the streaming service’s growing might. The film, not available in advance for review, sounds like a remake of “Alien Nation,” with Smith playing an L.A. cop on patrol with an alien partner. The two stumble across a magic wand, which we assume gives the action star an opportunity to zip back to his “Men in Black” heyday.

Holding down the fort

Former attorney Peter Moffat, whose BBC drama “Criminal Justice” inspired HBO’s “The Night Of,” makes a case for the British Royal Military Police in “The Last Post,” one of the few new series debuting during the holiday week. The six-part story spotlights English officers battling snipers and heatstroke while occupying current-day Yemen in the mid-1960s. Base life can be deadly dull, but Moffat breaks the monotony with some sweaty sex scenes.

Inconvenient truths

“MythBusters” wouldn’t dare ruin the Christmas weekend by exposing Santa Claus as a fraud, but the truth-seekers have plenty of other ground to cover in a megathon that stretches over nearly two weeks, starting with the very first episode in 2003. The series ended its original run in 2016.
