I was curious to see how sci-fi was done in 1929. (Might not have watched it, but for Lionel Barrymore.) Considering the time and Jules Vernes' story I was surprised at how reasonably farsighted Barrymore's character was when he was describing his invention and his take on human (and humanoid) evolution. Also the special effects were not bad, also considering the time this was made. Loved the various pressure suits!
