求外语高手来翻译

Those who are invisible in the backstage will appear in the limelight one day.
（这句译文的字面意思是：幕后默默无闻的终有一天会站到镁光灯下。）
这样翻译可以既表达原文的意思，又保留原文中所用的与“表演”、“演员”相关的比喻，比较贴切。如果用“Every dog has its day.”与原文差的太远了一点，意译得太过了。

A supporting role will become a leading role sooner or later.

照字面表达不出意思。

不如用另一句俚语：

Everydog has his day, and every man his hour. 人人都有得意的日子。

Supporting role, eventually to become protagonists of the day

这个是美式英语
