Usually, films in a series include common elements, such as characters (i.e., the Frankenstein films), actors/actresses (Astaire & Rogers), or names in a title (the Pink Panther films), etc. Sometimes, a film series is based upon the same director (i.e., Robert Rodriguez' Mariachi Trilogy, or Baz Luhrmann's Red Curtain Trilogy), or it can be based upon the studio (i.e., Hammer's Dracula films).”
