The long arm of the law

“Traffic Stop” has been running on HBO throughout the month, but you may finally want to check it out after seeing it get mentioned on Oscar night. While it didn’t win the prize for best documentary short, this narrative about a black woman manhandled by police during a routine traffic stop packs a punch. If you’re only interested in winners, don’t forget that “Icarus,” which won best documentary feature, is available on Netflix.

2 p.m., HBO

Sam I am

It’s not hard to believe that Sam Rockwell took home the Academy Award for his stunning work in “Three Billboards Outside Ebbing, Missouri.” What is incredible is that the 49-year-old actor had never been nominated, despite a rich catalog that includes a stellar turn as a mass murderer in 1999’s “The Green Mile.” Tom Hanks also stars in this adaptation of Stephen King’s novel.

The name of the game

Casey Anderson may be a top-notch tracker, but he’s terrible with nicknames. Ignore his shortcomings while watching “The Mountain Lion and Me” and you’ll get a fascinating introduction to an animal that’s eluded many of the most dedicated wildlife explorers.
