Feature-length films are typically defined as movies that have a running time of 60 minutes or longer. However, there are several synonyms that can be used to describe such films. For example, they may be referred to as full-length movies, feature films, or simply features. Other synonyms that can be used include cinema, motion picture, big-screen production, or even blockbuster. These terms are usually used to describe films that are intended for theatrical release and have a high level of production value. In general, feature-length films offer a longer running time, more complex storylines, and higher-quality production values than shorter formats like shorts or TV shows, making them a popular form of entertainment.
