Rear projection

Rear projection is a filmmaking technique where a projected image is displayed on a screen behind the actors, allowing them to interact with the background while being filmed in the foreground. This method creates a sense of depth and realism in a scene, often used in conjunction with other techniques to enhance visual storytelling. It gained significant popularity in musical filmmaking, enabling filmmakers to blend live-action performances with vibrant, imaginative backgrounds.
