The Good Guy: George Bailey (James Stewart)

Regular Quote: "Merry Christmas, movie house! Merry Christmas, Emporium! Merry Christmas, you wonderful old Building And Loan!"

The Possession: Contemplating suicide, George is visited by a supernatural being. Sadly for him it's not a wingless angel looking to help him find the true meaning of life once more.

No, it's Amon, a particularly nasty breed of Christian-flavoured fiend, with the ability to appear as a wolf with a serpent's tail (subtle!) or a man with a Raven's head.

He forces George to run around vomiting fire, which is good for those who need their driveways cleared, but not so good when he burns down the Building And Loan.

Demonic Dialogue: "F**k Bedford Falls and all who live in it! Every time an overly cute child burns, a demon gets his horns! I'll make violent love to any woman I find!"
