altered states

Drew Barrymore made her film debut in Ken Russell's 1980 film, "Altered States." This sci fi thriller delves deep into the sensory deprivation research that is conducted by a scientist in isolation tanks, while being under the influence of mind altering drugs such as LSD. William Hurt plays Eddie, the Harvard scientist who is conducting these experiments on himself. The experiments begin to veer out of control when Eddie begins experiencing moments of de-evolution outside of his isolation tanks.
