A portmanteau film is a movie that combines several short films or segments into one cohesive feature. Each segment typically has its own storyline, characters, and style, but they are linked by a common theme or concept. This format allows filmmakers to explore diverse ideas and genres within a single viewing experience. These films often showcase the work of multiple directors and writers, making them a collaborative effort. Examples of portmanteau films include The ABCs of Death and Paris, je t'aime, where each segment reflects the unique vision of its creator while contributing to the overall narrative of the film.
