I guess a lot of stuff from my childhood.
TV shows like "Lost in Space," "Wild, Wild West," "Man from Uncle," "Combat!" etc. Or those comics from the Silver Age, like early Captain Americas by Jack Kirby or even the ones by Jim Sterenko. The very early Conan the Barbarians by Barry Smith. And of course, the classic rock of the 70s like Black Sabbath, Hawkwind, Captain Beyond, Uriah Heep, Nektar, Magma, and so on.
Just to name a few.
ETA: Oh! And pulp heroes like The Shadow, Doc Savage, and such.
And the sword and sorcery books of my youth by the members of SAGA, like Lin Carter, John Jakes, Jack Vance, and so on!
ETA II: Oh! Oh! And the Blade movies. And Terminator movies. And the Underworld movies. And the old Universal monster movies. The Creature from the Black Lagoon rules! And the old Hammer Peter Cushing/Christopher Lee Dracula movies!
ETA III: Oh! Oh! Oh! And Old Time Radio shows! I love those things!
