Arthur Rosenberg (played by Bob Balaban) appears in Altered States.
Arthur Rosenberg is one of Eddie's like-minded research colleagues and assists his early sensory-deprivation experiments. He later helps monitor Eddie's visions and responds to the destructive energy released by the final experiment. Arthur is also part of the couple whose earlier connection helped bring Eddie and Emily together. Mason Parrish (played by Charles Haid) appears in Altered States.
Mason Parrish is a fellow researcher who aids Eddie's early work with sensory deprivation and later participates in monitoring the experiments. He witnesses Eddie's increasingly extreme transformations and helps bring him home after the tank is destroyed. Mason functions as one of Eddie's scientific collaborators and friends. Echeverria (played by Thaao Penghlis) appears in Altered States.
Echeverria is Eddie's guide during the journey into the Hinchi hill country. He explains that the ceremony uses Amanita muscaria and sinicuiche, including the plant's association with deep memory states. His guidance brings Eddie to the indigenous ceremony where the experiment with the potion begins. The Brujo (played by Charles White-Eagle) appears in Altered States.
The Brujo is an indigenous elder involved in the Hinchi ceremony. He gives Eddie a root to hold, cuts Eddie's hand, and adds drops of his blood to the potion he is preparing. This ritual directly initiates Eddie's intense hallucinations and begins the chain of experiences that drives his later experiments.
