Trivia: The hotel chase and horse in the elevator scenes were actually filmed in two hotels in Los Angeles as opposed to Washington D.C. where the film was set. The building with the elevators is the Westin hotel near downtown, and the lobby chase was filmed at the now-demolished Ambassador on Wilshire.
Trivia: Jamie Lee Curtis at one point says "I married Rambo." Director James Cameron wrote the story for Rambo: First Blood Part II.
Chosen answer: He didn't really. Harry just knew he was heading up. He pressed the top floor to get the elevator moving and kept an eye on him on the way up. If the terrorist's elevator suddenly stops, Harry can press the button for that floor to stop his elevator.
