What is fx in film?

In film, "fx" refers to special effects, which are techniques used to create illusions or enhance the visual experience in a movie. This can include practical effects, like animatronics and makeup, as well as digital effects, such as CGI (computer-generated imagery). Special effects are integral to storytelling, allowing filmmakers to depict scenes that would be impossible or impractical to film in reality. They contribute significantly to the overall aesthetic and immersive quality of a film.
