跑龙套应该用background actor/actress 或者extra 比较地道。这词还有群众演员的意思具体解释如下，摘抄于wikepedia中的解释。A background actor or extra is a performer in a film, television show, stage, musical, opera or ballet production, who appears in a nonspeaking, nonsinging or nondancing capacity, usually in the background (for example, in an audience or busy street scene).配角就用suporting actor/actress,这个最地道了，奥斯卡颁奖典礼上也用的这种表达
