During the 1960s, I can think of only The Magic Sword (1962).
During the 1970s, Wizards (1977), and a terrible animated version of The Lord of the Rings (1978).
Arnold Schwarzenegger tore up the scenery as Conan the Barbarian (1982) and Conan the Destroyer (1984), and suddenly every bodybuilder who could read a script was being squeezed into a loincloth and given a magic sword to wield: Clash of the Titans (1981), Beastmaster (1982), The Sword and the Sorcerer (1982), Ator (1982), Krull (1983), Hercules (1983), Deathstalker (1983), The Blade Master (1984), Ladyhawk (1985), Iron Warrior (1986), Masters of the Universe (1987), The Barbarians (1987)...well, you get the idea.
The plots were simple 1980s man-mountain plots, with an evil wizard instead of a drug lord, and a weirdly-named Medieval world instead of Southeast Asia.
And they had a similar appeal for gay kids and teenagers.
2. The buddy-bonding is strong and powerful, more emotionally compelling than the requisite romance with The Girl. In Deathstalker, the Deathstalker (Richard Hill) is patently in love with Oghris (Richard Brooker). In The Barbarians, Kutchek and Gore (Peter and David Paul) never fall in love with anyone (else).
4. There is usually no fade-out kiss. The Barbarian is a creature of the wilderness. He saves civilization but does not reside there, so at the end of the movie, he usually moves on.
By 1995, the fad had run its course, along with the cinematic interest in man-mountains, as beefcake fashions returned to the trim and athletic.
