Tarot cards and symbolism in various films. Some cases are a bit more subjective than others, but I think they fit well enough. ;) There's a couple of synchronicities among these movies as well. Johnny Depp walks in on a "Hanged Man" only to be the "Hanged Man" in Pirates of the Caribbean. And Heath Ledger is hung by one leg in The Dark Knight and is the "Hanged Man" in The Imaginarium of Doctor Parnassus.
