The Oscars are six days away. Here is a peek behind the curtain of Hollywood’s big night that reveals five things you might not have known:

v Designated sitters: Cameras never find an empty seat at the Academy Awards, with a troop of seat-fillers at the ready to occupy any chair vacated by a bathroom- or bar-bound guest. A parade of extras in tuxedoes and gowns arrive hours before the show begins and are ready to swoop in and sit once the cameras start rolling.

v Stomach pains: Oscar guests are often hungry. It may be self-imposed, either because of nominee nerves or a skin-tight gown with no room for error or eating. Not all attendees are invited to the post-ceremony dinner at the Governors Ball, which means some famished guests end up asking their limo driver to head to fast food, fast.

v Stay in your lane: There are two paths on the Oscars red carpet: one for famous people, and one for everyone else. Stanchions and velvet ropes separate the recognizable from the not. Famous folks walk on the side of the carpet closest to the cameras and reporters.

v Writers, stat!: Live shows inevitably hit speed bumps, such as last year’s supersized-one in which Warren Beatty and Faye Dunaway presented “La La Land” with the top trophy that belonged to “Moonlight.” Such gaffes become fodder for the host, with a village of comedy writers backstage to help quickly craft witticisms.

v Winners, meet media: Oscar recipients are shepherded backstage for photos and video and to face a rapid-fire Q&A session with a packed room of journalists. While the winners clutch their award and, in some cases, a celebratory glass of booze, reporters hold up numbered cards to be called on by an academy representative.

“The Lost Tapes: MALCOLM X” (8 P.M., SMITHSONIAN): This documentary series uses rare footage of the civil rights leaders life to illuminate his work.

“The Alienist” (9 p.m., TNT): The team hatches a plan to catch the serial killer.

“Living Biblically” (9:30 P.M., CBS): The series premiere about a modern-day man at a crossroads in his life who decides to live strictly in accordance with the Bible.

“Good Girls” (10 p.m., NBC): In the series premiere, three suburban moms rob a supermarket for extra cash. Unfortunately, the market is already the territory of a local gang.
