Let's come up with absurd ideas for sequels

Titanic II - Rose finds herself in an alternate Earth where the ship is still afloat. She reconnects with Jack and co, and then the ship sinks (again). This time, she lets him onboard that piece of wood that saved her. They go on to have loads of children in New York, until one day they see that the Titanic is being rebuilt and ready for launch, so they book themselves to sail back to Southhampton on it. This opens the way for a whole series of Titanic movies.

Mac & Me Too - The alien and his wheelchair-bound sidekick make their decades-awaited return to have zany adventures featuring as many product placements as possible.
