Terry Johnson's Hysteria requires a cast who can perform and respond to both broad slapstick and stagy melodrama, often in the same scene. Fortunately for theater audiences last fall, director Patrick Walsh assembled such a cast for the Southwest Shakespeare production of this peculiar masterpiece, which reimagines the meeting between psychologist Sigmund Freud and surrealist painter Salvador Dalí. Despite stiff competition from a gaggle of thespians, all of them running in and out of doorways and bellowing, Beau Heckman stood out as an especially fabulous Freud, both fearful of and besotted by his own knowledge of the emotional world.
