Flash Gordon pushed the envelope a little bit like Liberty Meadows in recent times. Alex Raymond's original strip was amazingly risque, and one of its major preoccupations in its original trumphant series in 1934-1936 was the sexual -yes, sexual, more than romantic- triangles on the Planet Mongo. Ming the Merciless had it bad for Dale Arden, and pretty much any scantily clad aristocratic female on Mongo had the hots for the "white man from Earth", the "fair youth", Flash Gordon.
So in keeping with that tradition my EMPIRE OF PLANET X film is heading into MA territory a little bit, but only to honour the source material. :)
