 Further contention was caused by the hiring of surrealist artist Salvador Dalí to conceive certain scenes in the film's key dream sequence.However, the sequence conceived and designed by Dalí and Hitchcock, once translated to film, proved to be too lengthy and complicated for Selznick, so the vast majority of what had been filmed ultimately was edited out.Two minutes of the dream sequence appear in the final film, but according to Ingrid Bergman, the original had been twenty minutes long.
