According to his list of productions, Parry documented the project for Dupont (the manufacturer of the explosives used) under at least three titles: DEVIL BENEATH THE SEA, RIPPLE ROCK and CONQUERING RIPPLE ROCK. The precise differences between these three films (or versions) is not known. However, at least the first two films named are represented in the material accessioned here, which includes scenes from all phases of the project. These out-takes comprise about 7,350 feet in total.
