Sacha Noam Baron Cohen is a British comedian, writer, actor, sketch artist, and voice actor. He is most widely known for his portrayal of three fictional characters: Ali G, Borat Sagdiyev, and Brüno Gehard.

Baron Cohen's comedy career has been shrouded in controversy and his films have been banned in several countries. He has been accused of being racist, anti-Semitic, sexist, and homophobic; however, Baron Cohen maintains that he utilizes his characters as tools to expose the stereotypes and prejudices held by society.

This unauthorized biography follows Baron Cohen from his beginnings in Hammersmith, West London and Cambridge University through his television career on The Eleven O'Clock Show and Da Ali G Show up to the release of The Dictator. Although he is an intensely private man, seldom giving interviews out of character, what is known about his personal life is also explored and detailed.
