Welles usually worked 16 to 18 hours a day on the film. He often began work at 4 a.m. since the special effects make-up used to age him for certain scenes took up to four hours to apply. Welles used this time to discuss the day's shooting with Toland and other crew members. The special contact lenses used to make Welles look elderly proved very painful, and a doctor was employed to place them into Welles's eyes. Welles had difficulty seeing clearly while wearing them, which caused him to badly cut his wrist when shooting the scene in which Kane breaks up the furniture in Susan's bedroom. While shooting the scene in which Kane shouts at Gettys on the stairs of Susan Alexander's apartment building, Welles fell ten feet; an X-ray revealed two bone chips in his ankle.
