The use of practical effects versus computer-generated imagery (CGI) in movies has been a topic of discussion among filmmakers and fans. Recently, the debate has gained more attention due to the increasing use of CGI in films. This debate matters because it affects the overall look and feel of a movie. The use of practical effects can add a sense of realism to a film, while CGI can provide more flexibility and control.

What happened

The use of practical effects in movies dates back to the early days of filmmaking. Practical effects include the use of prosthetics, makeup, and pyrotechnics to create realistic scenes. In recent years, however, the use of CGI has become more prevalent. CGI allows filmmakers to create complex scenes and characters that would be difficult or impossible to achieve with practical effects. The use of CGI has also raised concerns about the lack of realism in some films. Some filmmakers argue that CGI can make a film look too polished and perfect, taking away from the overall realism of the scene. The debate between practical effects and CGI is not just about aesthetics, but also about the role of the filmmaker. Some filmmakers see themselves as artists, and believe that the use of practical effects allows them to have more control over the final product.

Why it matters

Practical effects can add a sense of realism and grit to a film, while CGI can provide more flexibility and control. The use of CGI can also affect the budget of a film, as it can be more expensive than using practical effects. The debate between practical effects and CGI is also about the role of the filmmaker.
