Themed movie marathons are events where a series of films are screened back-to-back, all centered around a specific theme. This theme can be based on genres, such as horror or comedy, or franchises, like Star Wars or Harry Potter. These marathons often take place in theaters, homes, or online platforms, allowing fans to enjoy multiple films in one sitting. Participants in themed movie marathons often dress up as characters or engage in related activities, enhancing the experience. They may also include trivia games or discussions between films. These events are popular for bringing together fans and creating a sense of community around shared interests.
