Citizen Kane

Citizen Kane2

Above: The partial set from Citizen Kane consists of a foreground doorway and the butler (Paul Stewart), while Kane (Orson Welles) stands on a distant soundstage floor.

Below: The final, deep-focus image was completed with a matte painting by Chesley Bonestell. The live-action elements of the doorway in the foreground and Kane in the background were optically composited with a painted hallway, columns, and floor. The distant reflection of Kane on the floor was painted as well.
