Arnold Schwarzenegger reveals his highest‑earning movie wasn’t an action blockbuster, but the 1988 comedy 'Twins', co-starring Danny DeVito. He and DeVito agreed to skip upfront pay in favor of backend profits—and it paid off, netting him over $40 million. Despite iconic roles in Terminator and Predator, it was this lighthearted gamble that ultimately lined his pockets the most. #arnie #terminator #dannydevito
