Literary Review - David Collard on Exorcism by Eugene O'Neill: Eugene O'Neill's Strange Interlude, written in 1923, was a four-hour psychodrama acclaimed for its modern use of soliloquy and unflinching approach to adultery, madness and abortion. That the Marx Brothers could so ruthlessly spoof O'Neill's recently established theatrical trademark - along with those poetic non sequiturs, the invocation of indifferent deities, a whiff of the ineffable beneath the hokey vernacular and the doom-laden register - tells us plenty about the cultural range and tolerances of 1930s cinema audiences, the Marx Brothers' hair-trigger sensitivity to intellectual pretension, the giddy extent of the 42-year-old playwright's celebrity and, finally, something about O'Neill's writing itself.
