A crossover film is a movie that combines characters, settings, or storylines from different franchises or universes. This genre allows fans to see their favorite characters interact in ways that wouldn't typically occur in their original stories. For example, a film might feature characters from both the Marvel Cinematic Universe and Disney collaborating on a shared adventure. These films often attract a wide audience by appealing to fans of both franchises. They can create unique storytelling opportunities and generate excitement through the blending of different styles and themes. Successful crossover films can lead to increased box office revenue and expanded fan engagement.
