WITH SPOILERS: Yes, last night on “Mad Men” Don Draper finally met his biggest nightmare. It wasn’t his past or any of the secrets he used to fear about his identity. It was his present. Little Sally, not so little anymore, caught him with neighbor Sylvia en flagrante. It’s an image that should put her into permanent therapy or turn her into a revolutionary. Don, the great philanderer, now has a secret with Sally. For the first time in six seasons he looks worried. Terrified, even. The whole Sylvia-affair is about to come crashing in on him. Will Dr. Rosen or Megan find out? And what about Betty? We have two episodes left.

“Mad Men” has notoriously not paid off on many plot twists in the past. Things just happened. But now, with the end near, Matt Weiner seems to be giving plot a little more urgency. Peggy and Pete, now both single, had a major moment together. Little addressed from the first season is the fact that they had a child together, which Peggy gave up for adoption. Now, on a mission with Ted, they’ve reconnected. Where will this lead? And Ted: obviously Weiner likes him and we do too. But now that we’ve met his family, you know he’s not going to leave them.

“Favors” (the episode title) had no Joan and little Roger. But we did get a little more Ben Benson, who’s gay (no surprise) and on the move. I still think he’s aiming for the Harry Hamlin character. And Bob has some kind of knowledge or past with Manuel, the man servant he assigned to Pete’s mother. She’s either actually sleeping with Manuel or fantasizing about it. I’m more worried about Pete’s hair.

And then there’s Megan. She is really out of it. Clueless. I fear for everyone when she wakes up to what’s going on around her. She and Dr. Rosen and maybe Henry Francis make me think Season 6 will end with a cliffhanger–“Who Shot Don Draper?”

Tony winning Best Play “Vanya and Sonia and Masha and Spike” must say goodbye to its star. Sigourney Weaver will exit the play next month. But the original end date has been extended until August 25th, so past Tony winner Julie White will step in to play Masha. Weaver has to get ready to make two “Avatar” sequels for James Cameron, and has stayed well beyond the time she ever anticipated. If you can, see her before she goes. She’s terrific as self absorbed Masha. When “Vanya” does eventually wrap up its Broadway run it will move to the Mark Taper Forum in Los Angeles, probably in January…

…A big surprise winner last night was Courtney B. Vance. He plays Hap Hairston in “Lucky Guy,” and is a lucky guy because he’s married to Angela Bassett. I remember when Vance debuted on Broadway years ago in “Fences” with James Earl Jones. Since then he’s been a regular on TV, but always came back to theater. Bassett was thrilled for him last night, and she is really a knockout in person. What’s she up to? Bassett is heading to New Orleans, she tells me, to play a voodoo witch doctor in “American Horror Story” on F/X, with Jessica Lange…

…Judith Light is now a back to back Tony winner. She won last year for “Other Desert Cities” and last night for “The Assembled Parties.” Each was for Featured Actress. The year before “ODC” she was nominated for lead in “Lombardi.” This is quite a career change from “Who’s the Boss?” her hit TV series of long ago, and her famous run on “One Life to Live” in the late 1970s. But she’s turned out to be Broadway’s secret weapon. This review changed her life several years ago: http://tinyurl.com/mw9kshx

It was Cyndi Lauper’s night at the Tony Awards. Her “Kinky Boots,” created with Harvey Fierstein, won Best Musical. Lauper won for Best Score. Billy Porter won for Best Actor. Lauper et al. beat “Matilda,” the British musical that might have won in a different year. But “Kinky Boots,” based on the little known 2005 movie, reflected what Cyndi Lauper is all about: equality and understanding. It also had great songs.

So what’s she doing next? “I’m going on tour,” Cyndi told me around 2am at an after-after party at the Bemelmans Bar in the Carlyle Hotel. One party raged around her, with Porter and his sister present, as well Tony nominee Shalita Grant from the Tony winning new play “Vanya and Sonia and Masha and Spike.”

The tour starts in San Diego on Wednesday and runs for a month. Then Lauper has a couple of weeks off before another month in Australia and its environs. There’s no rest for the weary.

Upstairs in a suite, another after party raged on, where Patti Lupone greeted winners and losers until she, too, “hit the wall.”

This year’s Tonys seemed like they were sending a message. The winners were people from theater who’d worked hard and long. The losers were talents who came from Hollywood. Certainly Tom Hanks not winning Best Actor for “Lucky Guy” was a surprise. “Lucky Guy” is an enormous financial hit, and Hanks got great notices. But Tracy Letts won for “Who’s Afraid of Virginia Woolf?” The revival, which also won Best Revival of a Play, closed a while ago. Letts is famous for writing “August: Osage County.” This fall, he’s joining the hit TV show “Homeland.” But he is far from a household name.

Someone told me that when Cicely Tyson, age 88, won Best Actress in a Play, Hanks quipped to another actor: “Don’t worry, we still have 40 years.”

Tyson, by the way, will carry on through September doing 7 shows a week in “The Trip to Bountiful.” At the Plaza Hotel after party. she and her posse sauntered in after doing interviews and had dinner near the dance floor. The music was booming. I asked Miss Tyson if she would try another play after coming back with such a success. She smiled widely. The answer was yes.

More news: Tony winner Julie White will come in for a departing Sigourney Weaver in “Vanya” very shortly. Weaver stayed much longer than she thought possible. She has two “Avatar” sequels to make. White will be in “Vanya” through its extended run, which ends in September. “Vanya” will pick up again next January, I am told, at the Mark Taper Forum in Los Angeles.

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.”
