“I’m King of the World!” (Titanic)

Now this one’s a shocker! Pretty much everybody who’s seen Titanic has repeated the iconic DiCaprio line “I’m king of the world” in one moment or another. It’s just the perfect quote to describe a single moment of euphoria.

But surprisingly, the line was not part of the script and was made up on the spot by director James Cameron. He made it up almost instinctively and asked DiCaprio to “just sell it.” The young DiCaprio did his best, and what was the result? One of the most quoted, recognizable, and memorable lines in the history of cinema.
