Trivia
Director Mike Hodges, referring to the numerous production problems that plagued the film, once called it "the only improvised $27-million movie ever made".
Dr. Zarkov's backstory was that he was a NASA scientist who was fired for his paranoid fantasies that Earth was going to be attacked from outer space. Sixty Minutes derided him as "A Poor Man's Billy Mitchell".
On Ming's console listing catastrophes, Typhoon and Hurricane are listed as separate items. Typhoons and Hurricanes are the same weather system and are just called by different names around the globe.
There are many blue-screen compositions where characters or items appear partly transparent. This is probably due to the copying process for the travelling mattes that were used to superimpose the effects shots over one another.
When Princess Aura is showing Flash how to fly the ship when they are traveling to Arboria, she tells him, "The left lever controls direction, and the right controls altitude". Moments later while still flying, Flash gets mad at Aura for not showing him how to use the thought amplifier, so he shoves the left lever forward. The ship responds with a nose-dive.
Flash Gordon: Prince Barin! I'm not your enemy, Ming is! And you know it yourself. Ming is the enemy of every creature of Mongo! Let's all team up and fight him.
Why do the Hawkmen use rocket cycles if they have wings and, therefore, can fly by themselves?
A
well Let's put it this way: you can walk, yet you still travel by car, don't you?As much as I like the previous answer, there was a small blurb explaining the rocket cycles in a pre-production note. Something about using them as emergency transportation for injured hawk-people who couldn't fly.
