One of the earliest films with underwater photography and one of the earliest adaptations of Jules Verne's story (though actually this includes elements from two of his stories including Mysterious Island). Captain Nemo (Allen Holubar) and his submarine Nautilus travels the seas in search of Denver (William Welsh) whose unwelcome advances compelled a princess to take her own life...
Professor Aronnax (Dan Hanlon) and his daughter (Edna Pendleton) are captured by Nemo after the Nautilus sinks their ship. At first they are prisoners of Nemo then they join him on his hunt under and above the waves including to a mysterious island where a wild girl lives (Jane Gail)...
An astonishing film with a lot of underwater footage, maybe a little too much for the sake of the pace of the film at times but this was a genuine first in film making so should be expected. The odd bit of silent movie style overacting should be expected as well.
