What intellectual property is used to protect a movie?

Movies are primarily protected by copyright law, which grants the creators exclusive rights to reproduce, distribute, and display their work. Additionally, trademarks may be used to protect the film's title, logos, and branding elements. Trade secrets can also be relevant, particularly for proprietary production techniques or sensitive business information related to the film. These protections help ensure that the creators and stakeholders can control the use and commercialization of their cinematic works.
