Booooo hisssssss the villain appears ….. Saruman, wizard colleague of Gandalf’s, fallen from grace and consorting with the Enemy in The Lord of the Rings.
Check that evil scowl! Thankfully we know from the book he is eventually brought down by his own ungracious disdain towards a faithful servant. Always remember to show gratitude to those who help you, even if you are a powerful evil villain! People can, quite rightly, get a bit upset about a lack of loyalty and gratitude.
