Il tesoro sommerso

I enjoy this movie very much and try to watch it periodically. As someone who took up SCUBA diving the year before this movie was made, I'd like to call attention to the fact that it is the first full length feature movie in which SCUBA was used. In fact, it was so early in the development of equipment that the tanks that they were using were smaller than the 72 cubic foot tanks that became standard for steel tanks.(There were other sizes.) Also, note the two hose regulators that are all but obsolete, the early flipper designs, and the primitive back packs. To some, the story may seem a little corny, but so were early aviation pictures and early submarine pictures. This considered, I think that the movie deserves look.
