here are some instances where i thought “wow, thats right out of warhammer” or "they look like soandso…"
Pathfinder: vikings were chaos dwarves, indians were woodelves
King Arthur: brettonians vs Crom the Conquerer’s army
Underworld Evolution: the vampires in the past looked like dark elves in their armor and crossbows, marcus was an obvious strigoi vampire
Devil’s Rejects: opening scene the firefly family looks very much like black orcs
Reign of Fire: dwarves or Empire trapped by dragons(possibly giant’s causeway scenario from shadows of albion)
300: the immortals looked like chaos undivided warriors with 2xhand weapons, the grenadiers looked like chaos dwarf mages, and xerxes’s ambassitor(not the black guy, the one on the palanaquin with a whip) looked like a chaos dwarf slaver
im sure i can think of more if i try.
