At mid-day the camera rehearsals begin. The lighting and sound engineers and the cameramen have been completing their preparations and now the actors rehearse with the full production facilities. The director is now in his production suite and from here, with the aid of microphone links, controls all the studio activities. At his side are the production assistant (who cues the cameras and sound, notes any alteration or problems and looks after timing) and the vision-mixer (who in accordance with the shooting script and the director’s instructions selects pictures from the four cameras). The producer’s view is shown in the right-hand picture below.

Rehearsals continue during the afternoon, after the tea break with the actors in full uniform and make-up. As necessary the director comes down on to the studio floor between rehearsals to give notes to the actors on particular points which require attention.
