Box office: “The Purge” made $36.9 million in its opening weekend, or roughly 12 times its budget. The Ethan Hawke starring thriller didn’t even have a premiere anywhere, no red carpet or party, nothing. “The Purge” also took in twice as much as “The Internship,” a movie shot on the Google campus starring Owen Wilson and Vince Vaughn. That movie came in fourth. Will Smith’s $150 million “After Earth” fell to seventh place in its second weekend on its way to total collapse and write off.  The premise of the “The Purge” is that by 2022 everything is so wonderful in the world that one night a year everyone is allowed to commit crimes. It’s the equivalent of Golden Globes night. (Just kidding!) “The Purge,” brought to us by the producers of “Paranormal Activity,” will be the most profitable film of the year. Those others, not so much.

Mayor Mike Bloomberg was too busy on Saturday evening to pick up his Tony Award “honor” at the annual night before cocktail party. That’s when the Tony Awards hand out the Lifetime Achievement Awards and give a little pep rally for nominees before their Saturday night shows. Real actors like Judith Light, Richard Kind, Kristine Nielsen, Tom Sturridge (with his actress mom Phoebe Nichols), Judith Ivey, Danny Burstein, Billy Magnussen, the four little Matilda’s, Shalita Grant and William Ivey Long managed to get over to an out of the way restaurant on West 33rd Street across from Penn Station.

Amanda Green, who wrote the much loved “Hands on Hardbody” wouldn’t have missed it. Neither did her Tony nominated Best Supporting Actress Keala Settle. And Diana Paulus, a shoo in Best Director for “Pippin,” and Best Revival of A Musical, had a coterie of fans waiting to talk to her. She’s just accepted a job to direct the original musical “Finding Neverland,” based on the movie. The show had an iffy try out, outside of London. Paulus is rolling up her sleeves and re-making it. It will be her first non-revival.

Bloomberg, meantime, sent New York City Film commish Kathryn Oliver. Where was he? In Bermuda? Riding a Citibike? Drinking a Big Gulp? Oliver said he had a “prior commitment.” But you know he’ll be there tonight on national television to accept his award. Ditto “Normal Heart” playwright Larry Kramer who told the producers he’d only accept if he was on national TV. West 33rd St. ? What? Are you kidding?

Today all the Tony nominees are in rehearsal at Radio City Music Hall from 8am until 2pm. Then most of them have 3pm matinees. Yes, there are matinees on Sundays even on Tony show day. When the shows are over they come right back to Radio City for the red carpet. The show starts at 8pm.

By the way: the nominees only get a plus 1. Billy Magnussen is bringing his mom as his date. “We bought my dad a ticket in the mezzanine,” he told me. Judith Ivey is bringing her daughter. And so on.

The biggest applause in the jammed restaurant? For Paul Libin, who won a Lifetime Achievement award for his many years with Jujamcyn Theaters and working in various theater causes. Ivey Long, who kept announcing awards to people who hadn’t shown up, looked relieved. Libin stood up and said, “I am not a hologram,” and that went over big.

The movie going audience didn’t want to see “Wedding Crashers II” set on the Google campus. Last night’s box office shows that “The Internship” with Vince Vaughn and Owen Wilson is a huge misfire. The poorly reviewed comedy finished second, taking in $6.5 million. The two big stars weren’t a draw. Neither was the premise of two older guys working at Google.

Even though the movie was shot on the Google campus, people weren’t as interested as you might have thought. And there was the topical news hook of government internet spying this week. Still, it didn’t work. Maybe they shouldn’t have cut Eric Schmidt’s cameo.

The big news is that the #1 movie last night was a horror thriller from Universal called “The Purge.” It is not about vomiting or extreme dieting.

The director, James DeMonaco, has only one other movie credit and some TV credits. Ethan Hawke and Lena Heady star. “The Purge” caused an urge and took in over $16.7 million last night. And get this: it only cost between $3 and $5 million to make! Among the producers is our old pal Jason Blum, who also makes the “Paranormal Activity” films. He knows how to make these very low budget, high grossing phenoms. “The Purge” has also made well over $2 million in the United Kingdom.

Falling to sixth place last night was “After Earth.” But heading toward the $200 mil mark domestically is the fun and well made “Star Trek: Into Darkness.”

“After Earth” is quickly losing its orbit. The Will Smith movie, directed by M. Night Shyamalan, was a dud upon release last Friday. But yesterday– Thursday– the box office bottom dropped out. “After Earth” took a sudden dip to fifth place, rapidly losing steam on “date night” as movie goers finally rejected it completely. “After Earth” actually lost ground to Fox’s animated “Epic,” which picked up 25% more ticket goers from Wednesday and jumped into third place. “After Earth” is likely to drop substantially tonight, with figures this weekend that should just about kill it domestically. So far “After Earth”– which carries a price tag of $150 million approximately– has $36 million in the till. Its only foreign release so far is South Korea. Stay tuned for the final numbers on Sunday and what they mean…

The great Mel Brooks told me last night at his AFI tribute that he still has lots of plans for stage shows. Brooks said first of all that “Blazing Saddles” may yet make it to Broadway.

It’s not quite a linear movie like “The Producers” or “Young Frankenstein,” so it’s taking a bit longer to figure out. But my guess is we’ll see “Blazing Saddles” by 2015 at the latest, and probably earlier.

And Mel is hoping to bring “Young Frankenstein” to the West End in London. He’s in talks now. I loved “Young Frankenstein” as a musical. It got mixed reviews in New York — mostly because everyone wanted “The Producers” part two.

Brooks is very busy, very funny and still on top of his game. Also, his son Max wrote the book upon which “World War Z” is based. Really, Mel should be making a parody of “‘WWZ” after the blockbuster runs its course this summer. Cloris Leachman as a zombie leader? Absolutely!

Sources tell me that Paris Jackson may stay in the hospital a bit longer than the required 72 hours. It sounds now like she will be there for at least a couple of weeks, I am told, maybe longer. She’s not crazy and she’s not suicidal. But she does need help and therapy and a plan for moving forward.

There are a lot of crazy things being written right now about Paris. Don’t believe most of it. For one thing, Debbie Rowe and Katherine Jackson are on the same page when it comes to the kids. I’ve heard this consistently from everyone. Katherine had already agreed to let Paris stay with Debbie this summer. Debbie, sources say, has been trying to work on Paris’s various issues.

It is true that TJ Jackson, the kids’ co-guardian, no  longer lives near the Calabasas house. He is about 80 miles away and is not seen at the house on a regular basis. That doesn’t mean there will be a change in guardianship of Prince, Paris and  Blanket. He is still very much on top of things.

Next Sunday, June 15th, there will be a Jackson family wedding at the Havenhurst house in Encino. TJ’s brother, Taj, son of Tito, will get married. Everyone in the family is invited. Who will show up? We’ll have to read X17online, where Randy Jackson has some kind of deal for photos. It’s unlikely Paris will be there, but who knows> A week is a long time. And Tito’s kids have been very close to Paris and Prince.

Meantime, there is talk that Paris was going to change schools at the end of this term anyway. I will let you know more about this soon.
