Ronald Reagan
Ronald Reagan said, "Mr. Gorbachev, tear down this wall!" Although what he was referring to was actually an iron curtain not a wall, he didn't much care for communists.
He was also an actor who became President, as prophesied, "an actor for President?" by Derek Flint in In Like Flint.
He is also known for classifing a fruit, the tomato, as a vegetable.
