Film trailers are short previews of upcoming movies. They are designed to raise awareness and interest in a film prior to its release in movie theaters. Trailers target the same intended audience as the film and are shown in various places like movie theaters, TV, online platforms and social media. The goal is to showcase a film's genre, unique selling point, and stars in a way that intrigues audiences without revealing too much of the plot. This generates buzz and encourages people to watch the full movie in theaters.
