The “Popeye” forearms are still there and the biceps are still bulging, but Arnold Schwarzenegger appears no longer able to carry a Hollywood movie to box office success these days.

The 66-year old former California governor’s latest effort, “Sabotage” was a huge clunker at the box office this past weekend, producing just $5.3 million in ticket sales in its opening weekend.

That was good enough for just a No. 7 showing — and was the third straight opening weekend bomb for the actor who, in 23 films he has starred in, has helped sell more than $1.5 billion in US tickets, according to the-numbers.com.

But many of those hits, like “Terminator” and “True Lies,” came decades ago.

Not even an appearance by Schwarzenegger on WWE’s “Raw” show days before “Sabotage” opened — in front of plenty of young males, his target demographic — could spark interest.

It didn’t help, of course, that the $35 million film, from Open Road Films, got terrible reviews.

Kyle Smith, in The Post, said the film “doesn’t make a lot of sense on any level.”

“Eighty percent of the mayhem in the movie turns out to be based on a mistaken assumption,” Smith wrote.

“The film’s script is so bankrupt of ideas and lacking in common sense that I couldn’t even tell you if the movie wants us to hate them or not,” said a review at Film.com.

The two previous Schwarzenegger bombs were:

»“Escape Plan,” a $50 million budget film from Lionsgate, which opened Oct. 18, 2013 to a first weekend box office of just $9.9 million.

»“The Last Stand,” also from Lionsgate, with a budget of $45 million, had an opening weekend box office of $6.3 million.

Schwarzenegger’s last big hit was 2012’s “The Expendables 2,” which pulled in a worldwide box office of $305 million — with overseas tickets sales outpacing US sales by nearly 3-to-1.

Which brings us to a very important fact.

The “Expendables” cast — a veritable geezer-fest with Sylvester Stallone, Chuck Norris, Bruce Willis, Jean Claude Van Damme and Dolph Lundgren helping Arnold carry the day — is still very popular overseas.

This despite the fact that the overage ages of the cast’s six big stars is 62.5 years old — just five years younger than the average age of the Supreme Court justices.

The overseas popularity of the group probably explains why “Expendables 3” begins filming in a few months.

Hey, you never know.

The Trolling Stones continues to sell out arenas worldwide — and they average age of the four wrinkly rockers is 69.5 years old.

That makes Schwarzenegger and his pals practically kids.
