Arnold Schwarzenegger revealed on Watch What Happens Live that the 1988 comedy Twins earned him the biggest paycheck of his career — despite taking no salary upfront. Instead, he and co-star Danny DeVito received backend profits, which Schwarzenegger said ended up being "well above" $40 million. The movie, which grossed over $216 million, marked Arnold’s first comedic role and iconic pairing with DeVito as genetically engineered brothers.
