Before one can even adjust to the tone of this hospital-set soap opera, the most colorful character introduced in the opening scenes is unceremoniously given the shaft (movie audiences in 1971 must have felt jilted at the altar!). The ticklish repartee that begins the picture gives hint this might be an R-rated "Letter to Three Wives", but things go soapy from there. Prominent brain surgeon on the West Coast (John Colicos, pursing his lips in arch defiance) has been arrested for the murder of his cheating wife, but what should the other doctors on the hospital's board of directors do when they need his talents to save a dying child--whose mother is the mistress of one of the married surgeons? Colicos doesn't strike me as the type of husband who would shoot his spouse and her lover out of jealousy--he's the type who'd want to watch and maybe join in. Adapted from Frank Slaughter's book, "Doctors' Wives" was considered pretty heavy stuff in its day, what with a sex-and-murder scandal, an interracial marital affair, a few naked bums, and surgery footage foisted at us in close-up. It has been written and directed in a desperately with-it fashion, testing the new boundaries in cinema without censorship. Aficionados of the '70s will no doubt enjoy Dyan Cannon's wicked gleam, plus a cast that includes Gene Hackman (who repeatedly slaps wife Rachel Roberts in the face with a newspaper after she confesses to a lesbian affair), Richard Crenna, Carroll O'Connor and George Gaynes as frustrated doctors engaged in a game of musical beds. Main theme "The Costume Ball", sung by Mama Cass Elliot, is a strange, haunting piece of music. **1/2 from ****
