网络上时不时会爆出一组照片，说是某某大明星的御用替身，又或是某个美女明星的裸替。这年头，原来做“替身”也可以出名的哦。替身其实也分好几种，有特技替身、光替，还有裸替。

　　A body double is a general term for someone who substitutes for the credited actor of a character in any recorded visual medium, whether videotape or film. The term is most commonly used in the context of head-to-toe (or nearly) shots involving nudity.

　　“替身”( body double ) 通指在录像带或电影等作品中代替演员出演某一角色的替身演员。Body double这个词多用来指代“裸替”。

　　More specific terms are often used in special cases; a stunt double is used for dangerous or sophisticated sequences. This is in contrast to a stand-in who replaces an actor for non-filming purposes such as scene arrangement and lighting adjustments.

　　具体情况不同，“替身”的说法也不同，危险或复杂场景的替身叫做stunt double(特技替身)。电影拍摄之前搭景以及调试灯光时代替演员到场的替身则叫做stand-in(光替)。
