Scripts for a new episode were issued the Wednesday before for a read-through, Friday was rehearsal day, and final scripts were issued on Monday. Burrows, who directed most episodes, insisted on using film stock rather than videotape. He was also noted for using motion in his directorial style, trying to constantly keep characters moving rather than standing still.[24] Burrows and the Charles brothers emphasized to the cast to "never assume that you're not being watched" because the camera would be focused on the actors at all times, so they had to always be reacting and "always be funny".[2] During the first season when ratings were poor Paramount and NBC asked that the show use videotape to save money, but a poor test taping ended the experiment and Cheers continued to use film.[25]
