One of the greatest achievements in comedy. A work of staggering genius, Dazzlingly inventive, Fizzing with ideas . . . Brilliant, I haven’t known many geniuses in my life. Some brilliantly smart people, but only a tiny handful would I class as geniuses. I would class Douglas, because he saw things differently, and he was capable of communicating the way he saw things, and once he explained things the way he saw them, it was almost impossible to see them the way you used to see them, It changed my whole life. It's literally out of this world
