Trivia: When Lockhart is in the sensory deprivation tank, the nurse that does a poor job of keeping an eye on him is reading "Der Zauberberg" by Thomas Mann, which obviously has at that point a common premise with the movie (the main character goes to a sanatorium in the Alps just as a visitor but ends up as an inmate). The novel was inspired by Mann's visit to his wife at a Swiss sanatorium which happened in 1912, same year as the picture fully unveiled in the finale.
