If you've seen the superbly hammy "Flash Gordon" remake from 1980, then you will recognise this as the base for most of that film. This version is a rather clunkily bolted together edit of the cracking 1936 serial and features the hunky Buster Crabbe in the title role, trying to keep his gal "Dale" (Jean Rogers) safe from the merciless "Ming" (Charles Middleton) whilst trying to keep himself safe from the preying eyes of Princess "Aura" (Priscilla Lawson). Although I did enjoy this, I much preferred the original serialisation. Each episode had that slight moment of peril at the end which we miss out on here, and the reduction from over 4 hours to just over 90 minutes does mean we lose quite a bit of the fun and drama of the story. Ever since I first saw these 40 years ago, I have wanted one of the rocket ships. They looked like flying irons with sparklers attached; but that was part of the charm. The acting was as wooden as the sets and the story was all about an wholesome derring-do with an inevitability to the ending that probably instilled in me my prevailing wish that the baddies should always win. (What did "Darth Vader" or "Jaws" do do deserve their comeuppance?). It's a great adventure film this, there is plenty of action and bearing in mind it is all but 90 years old, I really did find it flew by.
