A movie marathon is an event where multiple films are watched back-to-back in a single sitting. This can be done at home, in theaters, or during special events. People often choose a specific theme, such as a series of films featuring a particular character, director, or genre, like action or romantic comedies. Movie marathons are popular for gatherings, such as birthday parties or holiday celebrations, where friends and family come together to enjoy a shared experience. Streaming services and DVDs make it easy to access a wide variety of films, allowing viewers to create their own custom marathons.
