This is a public domain copy of the film with Eastman Color, very good sound quality and visualy it is very good with some choppiness in action sequences. Original film print was only 23 frames per second, and when digitalized frame rate was changed to 29.976 frames per second.

Regardless minor technicality issues, it is a good adventure film.
It is in Public domain because it was never registered with Library of Congress!
