 Before filming began, the cast was taken to Perc Westmore (qv)s  salon on a Sunday morning to have their hair dyed red. When it was  time to rinse the dye, the beauticians discovered that the water had  been turned off for the entire block because the street was being  repaired. Because dyes were so strong then, leaving them on could  have caused the cast to lose their hair. Luckily, someone suggested  diluting the dye with cold cream.
