The new movie “Filth” I did not see. I have a weak stomach. Bad stuff, bad words. Good about it are stars James McAvoy and Imogen Poots.

McAvoy: “You cry but also laugh with this. It challenges the audience. Drugs, drinking, the different things repel and revolt, and you hate the lead character. I loved it.”

Would you show this to your parents?

“My granddad found it fabulous. Best thing he ever saw. But he’s a bit idiosyncratic. Dark sense of humor.”

“We in Scotland have our own dirty phrases. I’m a big swearer. Lots of filthy words in real life. And not ashamed of it.”

“My favorite scene? Watching X-rated home movies, crying my eyes out about losing my wife, and there’s stuff about sexually abusing the wife of my best friend while at the same time I’m masturbating. It’s repulsive and disgusting. Really great scene.”

Imogen Poots: “I’m excited about my role. So surreal and peculiar. But we all know the best things in life are odd and chaotic.”

“The words are exciting. You become numb to them. Maybe in real life I have a potty mouth. You get into all aspects and experiences of dumb, dangerous, racy scenes, shock of understanding, lengths people go to juxtapose cruelty and fun. It’s exquisite. You take control of your nervous system. See how fragile it is.”

Would you show this to your parents?

“I have the world’s best dad. He gave me love, the best times. That’s why I’d never change my last name because it’s his. He loved the movie. I watched his face. He was totally in it. I was so excited watching him.”

McAvoy’s a Scot. Imogen’s a Brit. Must be something in the water over there.

Mayor’s right on time

A marriage equality evening. Copacabana manager Glee Ballard parked me with a guy whose blond wig outpouf’d Mme. Pompadour’s, another “proposed to my husband on the 14th Street crosstown bus,” a third with concrete boobs inside red sequins, across from a gent wearing a rhinestone crown.

In came de Blasio, who told me: “Make sure you say I was prompt. Exactly on time for this. Not a minute late. It’s 9 p.m. I’ve been going since 6 a.m., when I went to the gym. I’m absolutely on time. That’s my quote. On time. Not a minute late.”

Why’s Bill there? He checked his written speech, his cell, then: “I love this group. We know we have to take back New York. Eleven years ago, a couple married in Niagara Falls. Ontario side because in New York same-sex wasn’t allowed. Subsequently, they remarried here legally as it should be.”

“I’ve come to acknowledge if you’re involved in a good cause, and wrapped up in other causes, history’s on your side because you forced the issue.”

About the issue of his wife’s quotes in a current magazine? “Look, she’s terrific. In all our years I can say I rarely fight with Chirlane. Maybe once a year. In any case, we never let it get far. She’s great.”

Viola Davis’ new ABC series starts September. A law prof, her Episode 1 wardrobe shows she’s a tight-ass. It’s a snug-snug-snug don’t-mess-with-me-I’m-in-charge-here dress…Bill Nye, “Science Guy” buzzing about climate change, was UMass Lowell’s commencement speaker. In his honor, students wore bow ties from Beau Ties of Vermont.

Hair’s the pits

Anyone note Brad Pitt’s hair tint is flexible? Last year his warm brown head had blond streaks. Now dark brown, highlightless, total brunette. His scalp changes more than Katy Perry’s.

NY Health & Racquet Club signs read: “Only in NYHRC.”

Only in New York, kids, only in New York.
