Arnold Schwarzenegger reveals the movie that’s made him the most money

Arnold Schwarzenegger, who starred in blockbuster films like “Terminator” and “Predator,” surprisingly made the most money from his ’80s comedy film “Twins” — raking in more than $40 million.

The action star explained that he and co-star Danny DeVito were not paid a salary for the film, and instead got “a piece of the backend.”

“It was fantastic,” he said Monday on “Watch What Happens Live with Andy Cohen.” “We went all the way to the bank with that one.”

The backend means the 77-year-old actor and DeVito, 80, were paid a percentage of the film’s profits after it was distributed.

The 1988 comedy starred Schwarzenegger and DeVito as genetically engineered twins separated at birth who reunite as adults.

The movie, directed by Ivan Reitman, grossed over $200 million worldwide, according to Box Office Mojo.

It was also Schwarzenegger’s first stab at comedy after starring in action flicks.

He followed that up with movies like “Kindergarten Cop,” “Junior” and “True Lies.”

When Cohen asked the former bodybuilder if he had earned $20 million from it, Schwarzenegger scoffed.

“Oh, much more, come on! What’s the matter with you?” he jokingly said.

The “True Lies” star confessed that it was “more than” $40 million.

“It was more than any movie I’ve ever made, let’s put it this way,” he shared.

Schwarzenegger added that there had been plans for a sequel called “Triplets,” co-starring Eddie Murphy, but it was shelved “because the director Ivan Reitman passed away just before we wanted to start shooting.”

Last month, Schwarzenegger shared a photo of himself, DeVito and former British UK Prime Minister Tony Blair.

“I love bringing old friends together! It was fantastic to see my dear friend Tony Blair and introduce him to my brother, @dannydevito,” he wrote alongside it.

He can currently be seen in the Netflix series “FUBAR,” opposite Monica Barbaro, in which he plays a CIA operative on the verge of retirement.
