Roy del Espacio (1983)

In an unauthorized adaptation of the first two Flash Gordon story arcs, the world's greatest astronaut Roy is sent to Mars with Dr. Faz and psychologist friend Helena to investigate the cosmic rays coming from the planet. What entails is a space epic of recognizable proportions. The film is much more notable for being lost media due to contemporary negative reception, from amateur animation and the similarities to the above-mentioned American comic strip.
