A teaser trailer is a short promotional video designed to generate excitement for an upcoming film, television show, or video game. Typically lasting between 30 seconds to a minute, it offers a glimpse of the storyline, characters, or visual style without revealing too much detail. Teaser trailers are often released months before the main trailer to build anticipation among audiences. These trailers usually feature captivating visuals, intriguing music, and minimal dialogue. They aim to create buzz on social media and among fans, often leading to discussions and speculation about the project. Teaser trailers are commonly associated with major releases, such as those from Hollywood or popular franchises like Marvel and Star Wars.
