Jack could not play in a second Titanic movie because he died in the first one. The only way they can make a second is by stealing James Cameron version and make it where Jack survives. People cant come back from the dead. That is not how a movie works. I really dont think they are going to come out with a number 2 version of Titanic. I want to be a director when I am older. This is a idea you can have if you want to make Titanic 2. They have these two people who get married and go on this new ship called Titanic 2. They get on it and they hit a 20 story iceburg. Then the ship sanks just like on Titanic. When the ship breaks apart the cruise ship Carnival is right by it. Their is a little boat right at the end of the ship. The wave makes it hit the Carnival. Two ships sink and twice the number of deaths. Good idea huh. I could not tell you my whole idea just in case you steal it from me and make a movie called Titanic 2.
