Leonardo Di Caprio Titanic performance as Jack Dawson when Titanic Director Cameron said he needed the cast to feel as though they were really on the Titanic, relive its liveliness, and "to take that energy and give it to Jack,an artist who is able to have his heart soar".
Jack is portrayed as a homeless,poor man from Chippewa Falls, Wisconsin who has toured numerous places in the world, primarily Paris. He wins two tickets onto the RMS Titanic ship in a poker game and travels as a third-class passenger with his friend Fabrizio.
Jack Dawson is attracted to Rose at first sight and meets her when she attempts to throw herself off the stern of the ship. This enables him to mix with the first-class passengers for a night.
Tom Cruise expressed an interest in the character, though his superstar asking price was never taken seriously.Leonardo DiCaprio, 22 years old at the time, was brought to Cameron's attention for the Titanic Movie by casting director Mali Finn. Initially, he did not want to portray the character, and refused to read his first romantic scene on the set .
Cameron said, "He read it once, then started goofing around, and I could never get him to focus on it again. But for one split second, a shaft of light came down from the heavens and lit up the forest."
Cameron strongly believed in Leonardo DiCaprio's acting ability, and told him, "Look, I'm not going to make this guy brooding and neurotic. I'm not going to give him a tic and a limp and all the things you want." Cameron rather envisioned the character as a James Stewart type.
Rose: I love you Jack.
Jack: Don't you do that, don't say your good-byes.
Rose: I'm so cold.
Jack: I don't know about you, but I intend on writing a strongly worded letter to the White Star Line about all of this. You're gonna go on, and make lots of babies, and watch them grow. You're gonna die an old lady, warm in her bed. Not here, not this night. Do you understand me? Winning that ticket, Rose, was the best thing that ever happened to me... it brought me to you. And I'm thankful for that, Rose. I'm thankful. You must do me this honor, Rose. Promise me you'll survive. That you won't give up, no matter what happens, no matter how hopeless. Promise me now, Rose, and never let go of that promise.
Rose: I promise.
Jack: Never let go.
Rose: I'll never let go. I'll never let go, Jack.
