During the production of this film, technology was not at the highest level of development, so the actors often faced difficulties. Robert noted that he had to act in a real helmet, which was later supplemented with the help of computer graphics. While filming in one of the scenes, Downey Jr. completely plunged into darkness, and after that, the illumination inside the helmet lit up - at this moment Robert was almost blind.
