When Robert Mitchum got fed up with repeated re-takes in which the director Otto Preminger ordered him to slap Jean Simmons across the face, he turned around and slapped Preminger, asking whether it was this way he wanted it. Preminger immediately demanded of Howard Hughes for Mitchum to be replaced. Hughes refused.
Prior to a 6/21/11 airing on TCM, Robert Osborne revealed that this was the final film of Jean Simmons' under an undesired contract with Howard Hughes (he'd bought it without her knowledge from J. Arthur Rank Studios in England.) Her displeasure led her to cut her hair off, knowing that Hughes preferred long-haired leading ladies and thinking it might prevent him from utilizing her before the contract's end date. Instead, he put her in this film and she was given a wig to wear throughout. He also promised director Otto Preminger a bonus if he finished shooting before Simmons' contract expires, which he collected.
