Essentially, Dr. Evil was made up of just about every Bond villain cliché you could think of. The cat, the henchmen (most of them useless themselves), the convoluted plans that allowed escape rather than just simply killing the hero and winning. Hell, they even beat Bond to the villainous half-brother reveal.
George Harrison loved a comedy film so much that he would communicate with the doll of a main character in Beatles meetings when he lost his voice and left the actor behind the role in tears.
