Brooks: Yes, absolutely. Of course it is impossible to take revenge for 6 million murdered Jews. But by using the medium of comedy, we can try to rob Hitler of his posthumous power and myths. In doing so, we should remember that Hitler did have some talents. He was able to fool an entire population into letting him be their leader. However, this role was basically a few numbers too great for him –- but he simply covered over this deficiency.

Spiegel: Was he a good actor? | Brooks: Yes, as he convinced many millions of Germans. It's not without good reason that comedies about Hitler often concern actors who should play him. Just think about Charlie Chaplin's The Great Dictator (1940) or Ernst Lubitsch's To Be or not To Be (1942). There's no doubt about it, Hitler worked in the same branch as we do: he created illusions. | Spiegel: In a documentary film about the downfall of the German battleship the Bismarck, US director James Cameron referred to Hitler as the "greatest pop star of his time." | Brooks: There's something in that. Hitler must have had a magnetic attractive force, like a rock star he used his voice to spellbind umpteen thousands of listeners. So it's only fitting when comic actors make him the limelight hog of world history. We take away from him the holy seriousness that always surrounded him and protected him like a cordon. | Mel Brooks "With Comedy, We Can Rob Hitler of his Posthumous Power", Spiegel International (March 16, 2006) | Original article in English.
