Actors have to learn their cues (ie the last words of the speeches just before their own speeches) as well as their own lines.
演员不仅要记住台词, 还要记住其他演员的暗示.
When I nod my head, that's your cue to interrupt the meeting.
我一点头, 就是暗示你把会议中断.
I'll cue you in (ie give you a signal to start) by nodding my head.
我一点头, 你就开始.
