"The Hatter is focused on time, understandably, since the Queen of Hearts has accused him of being a time-murderer. This has added heft to the theory that a top-hat wearing inventor, Theophilus Carter, was the inspiration.

Next we come to the notorious “hatters’ shakes,” a result of poisoning from mercury used in the early days of hat manufacturing. At a recent news conference, Johnny Depp suggested that that was where “mad as a Hatter” came from. The Hatter is “this guy who literally is damaged goods,” he said. In the British Medical Journal in 1983, however, H.A. Waldron concluded that the Hatter did not have mercury poisoning. The principal psychotic features of this type of poisoning are “excessive timidity, diffidence, increasing shyness, loss of self confidence, anxiety and a desire to remain unobserved and unobtrusive.” The Hatter, he states, was “an eccentric extravert.”
