There is no music or any score in the movie until the very end. Until then, all the ambient sounds are ship noises.
The movie is introduced as based on a true story, and there was indeed a mysterious and bloody mutiny aboard a ship also named the Berwind, occurring in the year 1905. Per the news account of the time, the captain of the actual Berwind was the similarly named "E.B. Rumill," and the probable mutineer was named Henry Scott, names also used in the movie.
According to an article in the 7 October 1957 edition of the Los Angeles Times, Robert Ryan had been cast in the lead role.
This film failed at the box office, resulting in a loss to MGM of $273,000 (over $2.8M in 2022) according to studio records.
