Mittendorf was also repsonsible for much of the makeup and some costuming in the film. The figures of the Seven Deadly Sins, including Death- which was played by Brigette Helms- were actors wearing masks made from a new malleable wood material that had just been developed. The material could be sawed, grated, filed or planed. The same material was used for the construction of the robot, Futura, also played by Helms.The actress had to be able to sit, stand and walk in the costume. A plaster mold of the helmet was constructed, onto which the body was directly attached, which had several jointed, moveable segments as in knight’s armor. Much like a knight’s armor, however, the costume was very uncomfortable and Helms suffered greatly during the filming, enduring cuts and bruises from the edges. Mittendorf, who is one of the few remaining Metropolis crew members still living, continues to own the copyright for the robot’s design.
