Each character embodies the qualities of the archetype they represent. Begin with Tom Hanks in Forrest Gump as the Fool, Morgan Freeman in Shawshank Redemption for Temperance, and Julie Andrews in The Sound of Music for the Sun, and you'll find a perfectly suited character represents every card.
Movie Tarot contains 78 cards that work as a fully functional tarot deck, plus a booklet which explains the choice of movie stars and the deeper personality traits they embody, as well as information on how to interpret the cards and conduct your own readings.
Tarot cards have had a number of uses historically, including for card games, but today they are primarily used for seeking answers to questions, often as a quest for divine guidance or inspiration. Readers of all experience levels can experience the cards' answer being given in an uncanny way, revealing something hidden but recognisable in a situation or thought process. Therein lies the significance of the Major (22) and Minor (56) Arcana cards, unearthing "secrets" buried in the deeper realms of consciousness and experience.
