How did Klaatus spaceship door remain invisible?
The spaceship in the sci-fi classic The Day the Earth Stood Still (1951) was 25 feet high and was built on a studio backlot. It had to show no visible openings or hatches, yet had to open at certain times. The film’s art directors incorporated an invisible split in its sides that was sealed over with soft plastic and coated with silver paint. Every time the dome of the ship was opened or closed, film crew members had to reseal the split. It was an innovative design for the era.
