Jack the Giant Killer (1962)

It's not as polished as Columbia's renowned Sinbad films, but JtGK will likely appeal to fans of the sailor, regardless. The works not only share a common aesthetic, but the hero and villain of The 7th Voyage... (1958) is the hero and villain here, too, and director Nathan Juran shot both films.
Set (initially) in Cornwall, it's a fantasy film in which farmer Jack (Kerwin Mathews) aids a Princess (Judi Meredith) who's targeted by a butt-hurt evil sorcerer (Torin Thatcher), a man who controls a host of fantastical creatures, some of which are stop-motion animated. The cheapo Hallowe'en masks and costumes will be off-putting to some, but for fans of this type of thing I doubt that even Jack's unmistakably plastic sword will dampen the enjoyment.
