Production
Practical Effects
Special effects produced physically, without computer-generated imagery or other post-production techniques.
In Depth
These include animatronics, prosthetics, pyrotechnics, and miniatures. Audiences often find them more 'grounded' and realistic than CGI because they interact with real light and physics.
Example
"The rotating hallway fight scene in 'Inception' which was filmed in a real rotating set, not a green screen."
