Answer 1

The Running Man (1987), starring Arnold Schwarzenegger. The film is loosely based on a novel written by Stephen King, who wrote it under the pseudonym of "Richard Bachman".

The complete quote from the movie would be:

Amber: "[after Richards cut Buzzsaw in half with a chain saw] What happened to Buzzsaw?"

Ben Richards: "He had to split."
