Almost impossible to pick just one.
"7th Voyage" was the first RH film I ever saw (and at the theatre,
too!)
"Jason & The Argonauts" may be his most well-rounded. Never boring,
and that skeleton fight! Cool...
Gotta say though that "Gwangi" is my 'guilty pleasure' favorite. I'm
a sucker for dinosaurs. With cowboys and leggy Gina Golan thrown
in... yeehaw!
