goldfish
n.— «So how can you see both the interviewer asking his/her questions and the interviewee? The solution is a device called the reverse, the cutaway or the “noddy.” After the interview is over the camera and lights are shifted to another position, the interviewer asks the questions all over again and these re-shot questions are reinserted during editing. For reaction shots the interviewer simply looks where the interviewee was, or still is, and tries to appear as if he were talking to the person he’s just interviewed. For extra effect he can also do the “goldfish,” which is where he opens his mouth as if appearing to begin to ask a question and the editor cuts on that instant back to the interviewee.» —“5th Column” by Peter Luck Sydney Morning Herald (Australia) May 18, 1992.
