When cameraman Hal Mohr was shown how the climactic flood scene was to be shot, he objected on the grounds that it would place many of the extras in jeopardy. Mohr told the executives that while the trained stuntmen knew what to expect and could prepare for it, the ordinary extras would have no idea what was coming, and many would be hurt. When his objections were overruled, he quit the picture, and was replaced by Barney McGill. During filming of the scene, the huge torrents of water overwhelmed the actors; three were drowned, one was so severely injured his leg had to be amputated and almost a dozen had broken limbs and other serious injuries.
The "premiere" version, running 135 minutes, ran only at the opening engagement in Hollywood. By the time of the New York premiere some weeks later, the film had been trimmed by over 30 minutes. At least some of the cuts were of Vitaphone talking sequences that didn't work well. In particular, Paul McAllister (Noah/Minister) fared poorly, as all his talking scenes were removed.
February 1956, Jack Warner sold the rights to all of his pre-December 1949 Warner Bros.-First National films to Associated Artists Productions. But, AAP edited several scenes in this film, and the duration of 75 minutes. At the moment preserved 100 minutes of the film (which were restored), 35 minutes considered lost.
