Petulia is Richard Lester's ode to the Swinging Sixties: a time of psychedelic instability when neither those who were square, nor those who were hip, really had it right. George C. Scott is Archie Bollen, a divorced San Francisco doctor in the midst of "discovering himself." Julie Christie is Petulia Danner, a peculiar young beauty recently married into an established family. Archie's sterile apartment and detached, bemused manner exemplify his inability to emote. Petulia's forward nature and desperate tenderness betray her fear of her sullen, abusive, pretty-boy husband (Richard Chamberlain). The physician and the newlywed embark on a schizophrenic love affair amid Pepsi references, automated motels, roller derbies, and a cameo by Big Brother and the Holding Company -- but they never achieve the daring to truly change their lives.
