The great Elizabeth Hubbard has passed away at age 89. Her son, Jeremy, posted a notice to Facebook today: “I’m sorry to say with a broken heart mi mum passed over the weekend. Thank you for being an unmovable rock that guided me through life. I will try to honour your memory for as long as I live.”

She was nominated 11 times for Daytime Emmys for playing Dr. Althea Davis on “The Doctors” in the 60s and 70s, and Lucinda Walsh on “As the World Turns.” She was a powerhouse actress who chewed all the scenery and spit it out. Whatever scene she was in, it was hers. She came from the legacy generation of soap actors with extensive theater training, and it showed. She appeared on Broadway in 14 separate productions until joining “As the World Turns,” where she remained until the last day in 2010.

Aside from smaller roles in other New York soaps, Hubbard also appeared in some key movies, like “Ordinary People” and “The Bell Jar.” She will be sorely missed. Condolences to her family and friends.

Logan Roy is dead.

The patriarch character of “Succession,” based on Rupert Murdoch, was killed off tonight in the 3rd episode of the show’s fourth and final season.

Already the reaction on social media is overwhelming. That’s because this was the most emotional hour of television in years. The Roys have fought among each other in the most vicious way for three seasons plus the last two episodes. And the whole thing was about love, lack of love, approbation, yearning for it. And now, that part of it is over.

I’m sure over the next five weeks we’ll see the Roy kids each each other alive to take over the company and come out on top. It will make “Game of Thrones” look like “Mary Poppins.” But for right now, the show was written with such despairing eloquence, and acted the same, the second showing right now on HBO should push the ratings into the stratosphere.

What Jesse Armstrong, the writer and creator of the show, has done is hit a bullseye dramatically. The emotions are so real and raw and unexpected throughout the roller coaster of denial and reluctant acceptance there’s huge identification. Brian Cox made Logan such a royal, immortal figure that a sudden death seems impossible. But last night week it was kind of telegraphed when the group of them had their final meeting. Logan actually apologized to them all. Even though no one accepted it, it was his farewell.

Emmys for the show and everyone involved. Outstanding work.

There are no advance screeners for tonight’s “Succession.”

A few people in the press received the first four episodes in advance, but now they’ve evaporated. HBO is holding back for a reason.

Tonight’s episode will feature Connor and Willa’s wedding, although marriage is not guaranteed. The kids are always fighting among themselves and with Logan, although Kendall and Shiv don’t know yet that Roman has weaseled his way back into his father’s good graces.

The X factor character is Alexander Skarsgard’s Lukas Matsson, aka “The Swede,” whose company is supposedly buying Waystar. We’ve only seen him so far on the phone eating junk food and making veiled threats. Matsoon is a stand in for Spotify’s Daniel Ek, but better looking.

But something big is happening tonight, that’s for sure. I’ll try and live tweet it at @showbiz411 and be back on here at the of the hour to say what I can without giving it away for other time zons.

Last night’s “SNL” had a great start with James Austin Johnson as Donald Trump taking over the Last Supper. He compared himself to Jesus, “because all I did was be friendly to a sex worker.” It was Johnson’s best bit yet. His Trump is really a work of art.

Molly Shannon, a treasured alumna of “SNL,” returned as host after 16 years. But the show’s writing now isn’t subversive enough to catch her voice, so many of the skit were lackluster. A good one, with the Jonas Brothers, didn’t come on until almost the end of the show. It should have been much earlier. There were almost no references to her recent successes, like “White Lotus,” or her HBO show, “I Love That for You.” And Mary Katherine Gallagher got a passing nod. Head scratchers.

Bigger headscratcher: Jonas Brothers. Their first song was “Waffle House,” an ok uptempo number currently number 11 on iTunes. But the second song was like a 70s rock ballad. It was the wrong kind of showcase for their about to be released album, which for some reason is called “The Album.” They need new management. They’re either not getting good advice, or not taking it.

PS Loved Heidi Gardner’s “Weekend Update” cameo as the overworked office supervisor. She’s ready for an Emmy nomination.
