Three Christs begins by listing four barbarous techniques used on psychiatric patients in the 1950s and then introduces its protagonist, who has a battered face and is preparing for a disciplinary hearing. This introduction appears to forecast a rough series of flashbacks for both the viewers and Dr. Alan Stone (Richard Gere). Ultimately, though, the movie goes too easy on us and him.

In 1959, Michigan's state mental hospitals did actually hold three men who believed themselves to be Jesus. Social psychologist Milton Rokeach decided to treat them together, and later wrote a book, The Three Christs of Ypsilanti. Rokeach is the basis for the fictionalized Stone, and his book inspired the movie's glib and often clunky screenplay, written by Eric Nazarian and director Jon Avnet.

Three Christs benefits from a seasoned cast. Peter Dinklage, Walton Goggins, and Bradley Whitford clearly relish the acting exercise of impersonating people with schizophrenia. Charlotte Hope is also compelling as Becky, the recent psychology graduate who signs on as Stone's research assistant and stirs the erotic impulses of all three patients (and maybe her new boss, too).
