As Arnold Schwarzenegger recalled during his "Actors on Actors" appearance, it was his idea for him, his co-star, and director to take no salary on "Twins." After they agreed, the trio went to Universal with the proposition. As Arnie put it, "We all take the risk, and you have the larger ownership because you paid for it, you get 60%, we get 40%." That 40% turned out to be a lot of money. "Twins" made $216 million on a $15 million budget, which means it made its budget back 14 times over and made Ivan Reitman, Danny DeVito, Schwarzenegger, and Universal a lot of money. How much? Well, in Arnie's case, it remains his biggest payday yet, even after almost three decades. In 2025, Schwarzenegger spoke to Andy Cohen during an appearance on "Watch What Happens Live" (via Variety), revealing that "Twins" was the most profitable film of his career — at least for him personally. The film netted the star upwards of $40 million thanks to the gamble he and his buddies took. "Number one was 'Twins' because we got no money for the salary but ownership with a piece of the back end," he said. "It was fantastic. We went all the way to the bank with that." Asked if he made more than $40 million, the actor replied, "It was more than that. It was more than any movie I ever made." After that, Schwarzenegger re-teamed with Reitman for 1990's "Kindergarten Cop," another family classic that proved "Twins" wasn't a fluke. Ever since, Arnie has been able to take on pretty much any genre he likes, delivering yet more family-friendly fare with "Jingle All the Way," which became one of the best Christmas movies of all time. He'd also go on to become governor of California, of course, but by that time, nothing he did seemed all that surprising.
