1) 9/11 documentaries, all day, History. On the 19th anniversary of the World Trade Center attacks (shown her, here’s a 21-hour marathon. That includes two new hours, looking at the final two planes – one hitting the Pentagon, the other crashing in a Pennsylvania field. The rest are reruns, starting with efforts to rebuild on the site (7 a.m.) and to find the flag that was hoisted there (8). Especially moving are “Escape From the Tower” and “102 Minutes that Changed America,” at 4 and 6 p.m.
2) More documentaries, 10 a.m. to 6 a.m., National Geographic. Films view that attack through then-Mayor Rudy Giuliani (4 p.m.) and then-President George W. Bush (9 p.m. and 4 a.m.). Also, the new film about declassified contents of Osama bin Laden’s computers reruns at 10:03 p.m. and 1:03 a.m.
3) “MacGyver,” 8 p.m., CBS. In a rerun, Los Angeles’ power grid has been hacked, plunging the city into darkness. Complicating things: The code used was written long ago by Riley – now Mac’s computer whiz – during her hacker days.
4) “Great Performances: Romeo and Juliet,” 9 p.m., PBS. William Shakespeare was quite fond of words, you know, so it’s odd to see a wordless version of his story. This one is performed (beautifully) by the Royal Ballet. It’s filmed – not just a stage version – which allows extra chances to open up the action and catch individual reactions. The result is gorgeous, if sometimes repetitious.
5) And streaming. The French comedy “Family Business” starts its second season today on Netflix, wrapping up a busy streaming stretch. Hulu debuted the neatly offbeat “Woke” on Wednesday and Netflix launched “Julie and the Phantoms” – a fantasy musical from “High School Musical” director Kenny Ortega – on Thursday. That followed a swarm of five major series over the Labor Day weekend.
