Reports yesterday and today about “Ghostbusters 3” directed by Jason Reitman, son of original director Ivan Reitman.

Readers with long memories will recall we reported the plan for “Ghostbusters 3” in December 2009. Ivan Reitman told us then about the next movie, with all the old stars and new characters including Oscar, the son of Sigourney Weaver and Bill Murray’s characters.

It’s been brewing for a decade. In that time, the all-female “Ghostbusters” came out was destroyed by evil internet trolls.

But here’s the original story. “G3” is set for summer 2020. It should be music to Huey Lewis’s ears since he wrote the theme music, lifted by Ray Parker Jr. The original song is “I Want a New Drug.” (Parker had another hit, “Jack and Jill,” that sounded just like Sly Stone’s “Stand.” Hmmm…)

We had to come home to freezing cold temps to have a real Hollywood night last night in New York for M. Night’s Shyamalan’s “Glass.”

All the stars came including Samuel L. Jackson, James McAvoy, Sarah Paulson, and Bruce Willis, as well as Luke Kirby, who was getting lots of “hey-I-know-that-guy” handshakes from “Mrs. Maisel” fans. He plays Lenny Bruce, and very well. (I asked, he’s Canadian, with Brooklyn blood. That’s why it works.)

After the screening, Universal took the guests to Buddokan on Ninth Avenue, where were joined by Mrs. Jackson aka LaTanya Richardson, who’s getting standing ovations every night in “To Kill a Mockingbird.” And Sarah Paulson’s partner in life, the great actress Holland Taylor, regaled us with stories about her birthday gift from Sarah (a beautiful necklace).

Universal brought in the heavy guns for “Glass,” with all the top execs including Ron Meyer and Donna Langley crossing this great country by plane for the occasion. “Glass” is said to be tracking at a high level for this weekend, although snowstorms threaten the box office. Fans of “Split” and “Unbreakable” will not be disappointed in this double sequel. McAvoy, playing a sort of Incredible Hulk as Sybil, is outstanding, but so is the whole cast. They are very invested in “Glass” shattering expectations.

Sam Jackson, as you know, is the coolest guy in town. How many movies does he have this year? “Uh, five, I think,” he said, counting them as we dined on Buddakan’s delicious treats. Does he ever turn anything down? “Oh yeah. I have to, so all these actors”– he said, pointing around the room– “can work.”

Jackson said it was mostly fun making “Glass,” even filming in Allentown, Pennsylvania “wasn’t bad.” What’s the worst place he ever got stuck for a shoot? “Winnipeg,” he said, “in the winter.” Check out this photo of Sam from “Glass.” I told he looked a lot like Frederick Douglass. He said, sardonically, “I hear he’s doing great things now.” (wink wink)

Meanwhile, McAvoy was still hosting with the most even when I left, and the Paulson-Taylor entourage– who were having a fine time– exited. Bruce Willis checked out after a few minutes so he and wife Emma could get back to their kids in Westchester County.

The first trailer for “Spider Man: Far from Home” is here, and it’s a winner. Tom Holland takes Peter Parker to Venice, Italy, where he’s enlisted by Samuel L. Jackson’s Nick Fury to save the city of canals and bridges. Jake Gyllenhaal is the new villain. Marisa Tomei is back as Aunt May (now known just as May), and “Iron Man” actor- director Jon Favreau is her love interest. Coming this summer, on the heels of the animated “Spider Man: Into the Spider Verse.” RIP Stan Lee, who knew there would be an endless appetite for this story. In every format. All the time.
