Some of the characteristics that make Steampunk, IMHO, is science and adventures. So while this film is not Steampunk, it contains some of the characteristics of Steampunk. I would LOVE to see this remade as a Full Steampunk Aural-Ocular adventure.
You will have to have a good memory to recall this 1967 adventure flick. It IS available through Netflix, problem is, it looks like someone recorded it by aiming a video recorder at a TV screen. The name of the film is "Island of the Lost".
It contains a sailing ship, with a full scientific lab, pretty girls, a child and a pet seal, a strange lost island with never before seen wild animals (Which just happen to look like Dogs with Fans added to them, and flightless birds that oddly enough look like Ostrich with dangerous claws added to their feet.)
Should any of you have seen a High Quality version of this movie, please let me know. Even with a lower quality, it's still a great adventure film.
