Altered States

A Harvard scientist conducts experiments with sensory deprivation tanks and psychoactive drugs in his quest to access other planes of consciousness.

🧬 The novel was written simultaneously with the screenplay - Chayefsky developed both versions at the same time, which was highly unusual for that era. 🎬 Despite being known primarily as a screenwriter, this was Chayefsky's only novel. He won three Academy Awards for other screenplays, including "Network" and "Marty." 🔬 The isolation tank experiments depicted in the book were inspired by real research conducted by neuroscientist John C. Lilly, who performed consciousness experiments using sensory deprivation tanks while taking psychedelic drugs. 🎭 The story's protagonist, Eddie Jessup, was partially based on Timothy Leary, the controversial Harvard professor known for his psychedelic research and the famous phrase "turn on, tune in, drop out." ⚡ Chayefsky extensively researched genetic memory and anthropology for two years before writing the book, consulting with numerous scientists and anthropologists to ensure scientific accuracy in his work.
