By now, you've probably seen the Titanic a million times.
It's just one of those films that you can't help watching once it's on!
If you didn't know this already, originally Matthew McConaughey was supposed to play the role of Jack instead of Leonardo DiCaprio.
This fun fact was released that DiCaprio hated one of the most famous lines from the film!
Any guesses?
It's the one where he is on the front of the ship with his friend Fabrizio and shouts "I'm the king of the world!"
He said it was made up on the spot, and no line was working.
Director James Cameron said just say "I'm the king of the world and spread your arms wide, love it and celebrate it."
So he did, and it was extremely cheesy but it became one of the most famous lines!
