I didn’t watch the movie The Titanic for ten years because I already knew how it ended: the boat sank. Which is what makes the idea for a sequel that much sillier. Despite the 1980 movie Raise the Titanic and the 2010 film Titanic II (which is about another boat named Titanic II), people tried their hand at making a sequel to the 1997 disaster romance epic. Some are pretty good, considering what they had to work with. See several in this list I posted at mental_floss.
