The Movie: Dragonslayer (1981)
What Is It?: Complex and elegiac fantasy about a callow young man who must complete a journey for an old wizard so he can vanquish a virgin-eating dragon during a solar eclipse. The hilariously named Vermithrax Pejorative is the single greatest realization of a dragon on film.
Why Today?: On this day in 3340 BC, a solar eclipse is recorded in stone for the very first time at the Megalithic Monument in Ireland.
