John Wayne and Andy Devine were swimmers in the temple collapse sequence, but they are not recognizable among the hundreds of other swimmers.
Dolores Costello came down with pneumonia while working on this film.
One of the extras who survived the flood scene was John Wayne.
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.
This film has been preserved by the UCLA Film and Television Archive in conjunction with the project American Moviemakers: The Dawn of Sound.
Three extras drowned during the filming of the flood scene.

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.
