The Wizard of Oz (Of course! The 1939 film)
Return to Oz (underrated, and tries to do the impossible, payimng homage to both the books and the 1939 film)
Seventh Voyage of Sinbad, and the other two Harryhausen Sinbad movies, Golden Voyage of… and …and the Eye of the Tiger, which aren’t nearly as good. Sventh Voyage provides one of the best pre-CGI dragons.
Jason and the Argonauts – the Harryhausen film, again, bot the TV CGI movie
Clash of the Titans – It’s got Medusa! How can I not love it? Also, the biggest bevy of stars ever in a Harryhausen film, and the best live-action writing and direction in a long time.
The Seven Faces of Dr. Lao – not as good as the Charges G. Ginney book, but not bad.
The aforementioned Dragonslayer. If you do like drahgon’s, you’d love this.
The Sword and the Sorceror – all the good parts are stolen from Conan stories (this film just beat the first Conan movie to the theaters). One of the nobles is played by Fontaine from Murphy Brown! And Richard Mull of Night Court plays the Evil Magician! With an incredibly stupid triple-bladed rocket-propelled sword!
Sorceress – there are at least three films with this title. I refer to the circa 1981 Roger Corman film. It looks as if it was filmed in some little European country and dubbed into English, but it was actually made in the USA. With awful makeup, models, and dialogue. And cheap special effects!
Jack the Giant Killer – an attempt to rip off Harryhausen’s Seventh Voyage of Sinbad, by hiring away the star (Kerwin Matthews), the villain (Torin Thatcher, with hair for once), and the director (Nathan Juran). Jim Danforth provides the less-than-Harryhausen animation. I have fond memories of this from when I was a child that re-viewing does not sustain. The Dragon at the end has big puppy-dog eyes, like the Luck dragon from never-Ending story. the leprechaun who speaks only in rhyme is mock-worthy. With witches, two giants (one with two heads), witches, a viking, and a sea monster. There was reportedly a version that they dubbed singing into, but I’ve never seen that.
The Sword and the Dragon – US-titled release of the Russian film Ilya Mourometz that i grew up watching (a lot of the voices are provided by the omnipresent Paul frees, so the leader of the Tugars (Mongols) sounds suspiciously like Boris Badenov. MST3K covered this one, but it’s not on any of the commercially released discs – you’ll have to go to the gray market to buy that. With a surprisingly good triple-headed fire-breathing dragon.
The Wonderful World of the Brothers Grimm – a George Pal production that was originally in Cinerama, and suffers from reduction to the small screen. It has a Jim Danforth-animated dragon, and some other animated effects. With Buddy Hackett(!!)
