Ey, Cromulus, that is true! But did you know that "The sword and the sorcerer" was released BEFORE the Milius' movie?
And "The Beastmaster" was filmed before "Conan the barbarian" was released,
and it's amazing how many apparent relations both movies has. Some scenes look almost copied.
I've been wondering how could these movies be influenced by CTB if it was not yet released. Maybe some trolls or spies in the Millius' movie production?
Anyway you can allways assume that it just a coincidence, or maybe these topics where around the unconcious minds of everybody at these times... Who knows.
