Genres and Topics
Movies set in Halloween, or in which Halloween is central to the plot. These are usually horror movies. Movies concidentally featuring Halloween are not included in this topic.
Topics are sub-genres and/or themes of any kind (romantic comedy, buddy, sports, etc.) that describe the plot of the movie you are looking for. Topics, however, are not keywords. If you search for a topic like "shark", for example, only movies in which sharks play a significant roll will appear, such as 'Jaws'. But not every movie that has a shark in it will be listed.
