someone who performs stunts (= exciting dangerous actions) instead of an actor in a film or television programme

They put in stunt doubles for the climactic fight scene. 他们在高潮的打斗场面中安排了特技替身。

I later found out that my stunt double had refused to do the jump because of the potential danger. 我后来发现，我的特技替身拒绝跳跃，因为有潜在的危险。
