They ref Tolkien, Norse mythology, Greek mythology, and Arthurian legends in their songs. Those British boys loved the fantasy vibe.
I have no doubt that this true. I also have no doubt that this is not the reason "Whole Lotta Love" was picked for the clip.
My best guess is that it's a throw-back favorite of some decision-maker associated with the show who never saw Led Zeppelin "live." If anyone does know why it was picked, I would genuinely love to know. Until then, I'll have to assume it's a lot cheaper to source classic rock than to write an original score.
