The Mad Hatter has arrived in "Gotham." In the first photo of the character, "The Walking Dead" star Benedict Samuel dons the character's iconic hat and jacket for his debut in "Gotham" Season 3's third episode.
According to Entertainment Weekly's official description of the character, Mad Hatter is "a talented hypnotist teetering on the edge of madness. He arrives in Gotham with an unwavering desire to find his sister, Alice, a young woman who went missing in the city years ago. It is anyone's guess just how far down the rabbit hole he's willing to go in order to find her."
In the comics, Tetch -- aka the Mad Hatter -- is a scientist that uses his own mind-control control technology to control the minds of his victims. Though based on a children's book character, the character is sometimes portrayed as being severely mentally ill, with an underlying darkness to him. The character, who was co-created by Bill Finger, debuted in 1949's "Batman" #49.
