Overview
In filmmaking, a double is a person who substitutes for another actor such that the person's face is not shown. There are various terms associated with a double based on the specific body part or ability they serve as a double for, such as stunt double, "dance double", "butt double" and "hand double".
Types of doubles
Body double
A body double or photography double is used in certain specific shots to replace the credited actor of a character. The body double's face is obscured to maintain the illusion that they are the same character; usually by shooting their body at an angle that leaves their face out (such as by showing the body double from the back) or in post-production by superimposing the original actor's face over the body double's. The double's face is usually not seen on-camera, particularly when they do not facially resemble the actor; a wig will usually be employed if the double's hair color is different from that of the main actor. This is in contrast to a stand-in, who replaces an actor for non-filming purposes such as scene arrangement and lighting adjustments.
