“Conan The Barbarian” with Arnold Swarzenegger because that movie came out at a time when we were playing D&D all the time in high school.
I know the Rankin & Bass cartoon of “The Hobbit” and Ralph Bakshi’s “Return of the King” also had an influence.
“The Vikings” with Kirk Douglas and Tony Curtis and any other movie from the 50’s and 60’s on TV at the time.
As I write this, “Excalibur” comes to mind. We laughed at the scene of what a king does in full armor, but the armor and the fighting was cool.
“Monty Python and the Holy Grail” was good for the wacky side of things.
I am sure there were others, but I don’t recall them at the moment.
