Underwater

Undersea Kingdom

Inspired by Flash Gordon and The Phantom Empire, the young Republic Studios launched their own sci-fi serial in 1936, and the result was an action-packed, but rather brainless concoction. Occasional good design and an energetic Crash Corrigan can’t save this badly scripted Atlantis-themed hodgepodge. 3/10

Gold

This smart, well filmed and very successful 1934 film marked the beginning of the end for German science fiction before the Nazis banned the genre. Best remembered for its impressive futuristic sets and superb effects, this film is on the talkier side. It’s secret weapons are German superstars Hans Albers and Brigitte Helm. 7/10.

The Mysterious Island

Borrowing the name of Jules Verne’s bestseller, this problem-ridden 1926-1929 production features good acting, some remarkable special effects and a solid-ish script, but alas, the schizophrenic semi-talkie-semi-silent film is just as equally horrible in many ways, with toy submarines and crocodiles substituting for dinos. (4/10)
