Have you seen Titanic, the one from 1997 that James Cameron did?
Yes! I did. It's a great film!
Cameron's inspiration came from shipwrecks.  He was fascinated with them.
I didn't know that, but I'm not surprised.
He shot actual footage from the real Titanic wreck for the movie.
Wow, that's cool! The underwater wreck scenes were just a few of the many great scenes
They also used scale models and computers to re-create the sinking.
It looked really good and believable - especially for 1997.
