Note that the DVD copy from Alpha Video is a bit rough--scratchy and a bit blurry. So, you really must want to see this film if you bother buying this one! I was quite surprised by "The Lost Atlantis", as I expected quite a bit from it since it was directed by the famous G.W. Pabst--the same guy who directed Louise Brooks' famous films ("Diary of a Lost Girl" and "Pandora's Box") as well as the brilliant German dramas "Kameradschaft" and "Westfront 1918". Instead, I found the film to be quite dull and lacking momentum. In other words, it has an unusual but interesting idea but is so poorly paced that I found myself losing interest as the film progressed. My assumption is that this will happen to you, too, if you decide to watch.
The premise of this film is that Atlantis was not lost in sea but covered in the Sahara Desert. And, unknown to outsiders, this bizarre land still exists--and is ruled by a goofy lady named Antinea (Brigitte Helm). For the most part, folks just sit around in this land doing nothing while Antinea spends her time jerking men around because you assume she has nothing better to do. If she says to kill, they do--and it's all VERY slow and mysterious--with LOTS of staring from Antinea. In fact, she rarely talks (possibly due to her strong German accent) but lounges about and makes men dance because she is, supposedly, so exotic and enticing. Yeah,...whatever.
All in all, this is a pretty bad film. The plot is WAY too slow, the acting way too poor and you wonder how Pabst could have made such a film. I was hoping for a strange escapist sort of film (like "She", 1935) but instead it was just boredom from start to finish.
FYI--Helm was famous as the lady who was the evil robot woman from "Metropolis". However, in "Metropolis" her performance was much more human and emotive!
