This is an engrossing film with a very intriguing premise: if you treat 3 paranoid, schizophrenic patients each of whom thinks he is Jesus Christ isolating them from other mental patients in a state hospital, will one dominate the others or will they learn to bring joy, hope and companionship to their fellows? Dr. Alan Stone and his Psychology intern, thinks he can do the latter.
This story unfolds in the 60s when the accepted treatment for psychiatric patients is harsh and inhumane by today's standards. It consisted of either shock therapy, use of drugs or lobotomy. Dr. Stone would not have none of those because he believes these so-called clinical protocols simply "warehoused" the patients, not treated them. He believed rather in exploring their mind, understanding it by means of gentle interactions with the patients. The establishment thought this was crossing the boundary of "normal clinical protocols." But he asserts that without risks, there can be no breakthroughs.
Peter Dinklage stands out as patient Joseph Cassel. He inhabits the role and you deeply empathize with him and what happens to him. The same is true with Walton Goggins as Leon Gabor with all his pent-up libidinal urges and philosophical ruminations about identity. And we certainly relate with Richard Gere as Alan Stone whose persistence amidst resistance from his colleagues is commendable.
So, the question that the viewer asks is, did he succeed? There's only one way to find out.
