John Hurt’s new sci-fi movie “Snowpiercer” is about ice age, global warming and killing earthly life. Asked to codify this he replied: “Well, that’s not really my job.” Eventually he sort of explained it as:

“I have to believe in global warming if one is to believe in science. This is a graphic novel on which to found a simplified, not intellectual story on humanity. Not difficult to understand. It just is what it is.”

Goody. Makes it much clearer . . .

“It’s more than just a genre piece, which must find its own whatever truth on a particular level. A bit Hitchcockian, this is an extremely clever work. No wastage.”

Absolutely. Now I see . . .

“Harsh. Quite masculine. Brutal. Best described as strong, violent. Not too many bad words in it.”

And Mr. Hurt’s role?

“A lowly actor playing a complicated character who’s part of the whole makeup of this global train perpetually traveling around covering the earth saving only those few aboard. Only the non-violent get through the net.

“Tilda Swinton and Ed Harris are in it. We filmed entirely, four months, in Prague. The food’s excellent there.”

And when not in Prague, where’s home?

“England. Norfolk. Where I walk, read, paint what is expressionist by nature. I don’t offer my canvases for sale. And for this film I’m coming to New York, one of my favorite cities, where, unfortunately, I rarely spend much time because I’m set to do a Tarzan film in England.”

I so look forward to our next chat.

Must eats & J.Lo notes

Mimi Sheraton’s written the sweetly titled book “1,000 Foods To Eat Before You Die” . . . Should anyone ask, anyone should know Jennifer Lopez’s favorite childhood actress was Rita Moreno . . . Matt Groening, creator of “The Simpsons” characters: “Although tattoos are a cartoonist’s ultimate compliment, I get upset if my character’s name is misspelled.”

Booking Mary Todd

OY! If you haven’t stomach’d enough about Honest Abe, this fall brings Plume’s “Mrs. Lincoln’s Rival.” Author’s Jennifer Chiaverini, whose previous outing was “Mrs. Lincoln’s Dressmaker.” Considering only a few of us were actually around in Civil War days, go separate historical from theatrical. Meanwhile, let us eagerly await what could be her next, “Mrs. Lincoln’s Orthodontist.”

Dine & dish

Jerusalem. Alan Dershowitz lunching with Barry Slotnick, who once rep’d Israel’s former prime minister Ehud Olmert, then dinner with current PM Netanyahu . . . “A Gentleman’s Guide To Love and Murder” won’t guide anyone backstage. They barred a behind-the-scenes interview . . . Robert Pattinson’s snack: a cuppa Misugaru — drink featuring multigrains, black sesame, black beans, black rice, barley at Union Square’s Caffé Bene coffeehouse.

Lady governor?

A Kirsten Gillibrand ­e-mail’s around saying “only 32 women have ever been elected governor.” Says nothing else. Since a woman, Zephyr Teachout, is trying to get on the ballot to challenge Cuomo in a Dem primary, sort of almost appears the senator wants a woman as gov — not Andrew.

Big baloney

A rumor’s around that Sec’y of State John Kerry has a big ego. Untruth. B.S. Unqualified hooey. However, what I do know is that last week he attended a séance — and held his own hand.

In our East End the hills are alive with the sounds of misery. Southampton infected with Kardashianitis. Now Clintonitis plaguing Amagansett. Locals are feverish over security, traffic, police and sightseers.

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