Whenever a film is a box-office hit, the natural next step is to make a sequel. And the majority of the time that sequel has roughly the same cast, at least when it comes to the leading roles.

Whether they like it or not, directors have to deal with the fact that actors aren't always keen for a sequel, even if the first film did well.
