During one of the scenes at night, background actors continued to walk off screen, once they were completely off screen the Director, Whit Whitman, yelled for them to "hold". And he told the remaining two actors to "continue", the background actors heard the word continue, and they started walking again. The Director yelled "hold", and then told the two actors to "continue" once again, and the background actors continued to walk again. Out of frustration, the Director yelled at the background, and told them not to move no matter what they heard! The onset joke for the rest of the filming was... "Hold... Continue!" In retrospect, Whitman realized his mistake by not informing the background what to do during the scene, so as soon as it was over, he immediately walked over and apologized.
