The film opens with a sea battle, and a submarine going down, and for a large part of the remainder of the movie, we follow captain Schlemmer(Fred Vogeding) and Steve McCreary (Ralph Bellamy) as they try to bring its contents back up years later. Our female lead Diane Templeton is the lovely (and in this one, also educated and wealthy) Fay Wray. She will provide the ship and the money for her undersea research, or so she thinks. She had been making movies for 10 years by this time, although it was only Bellamy's second year. In 1933, Wray would make eleven films (wow!) Writer Jo Swerling had written numerous adventures from the 1920s to the 1970s, including portions of Gone With the Wind, and It's a Wonderful Life. Good strong script, mostly good acting; A couple scenes are a little fuzzy and out of focus, but it was 1933. Also a little naughty for its time, especially in the photography dark-room. Interesting discussion of evolution from Diane Templeton, as she shows McCreary around some laboratory. Good action film. Per IMDb, it appears to have been re-released in 2005, but I was not able to find it available on barnes & noble, ebay, or amazon.com in any format. The web page for "nothings new video" says they are no longer in operation.
