Film acting is the art of performing in front of a camera to create a movie. Actors portray characters by using their voice, body language, and emotions to convey a story. They work closely with directors and other crew members to bring the script to life, often rehearsing scenes multiple times to perfect their performances. In film, actors must adapt to various techniques, such as hitting marks for camera angles and delivering lines with precise timing. They may also collaborate with screenwriters to develop their characters further, ensuring that their portrayal aligns with the overall vision of the film.
