 The film ran over schedule and budget due to mishaps caused when  director Preminger, Otto (qv) insisted that actors perform their  own stunts for the scenes of the raft struggling down the rapids. On  one occasion, Monroe, Marilyn (qv) had to be saved from drowning  when her boots filled with water, and on another occasion, she and  Mitchum, Robert (qv) had to be rescued when their raft became  stuck on a rock and was on the verge of overturning.
