Gotham has cast Benedict Samuel (who played the Wolves’ Owen in seasons five and six of The Walking Dead) as classic Batman villain The Mad Hatter, aka Jervis Tetch.
The Gotham version of the character is described as follows: “Tetch 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, the Alice In Wonderland-inspired character debuted in Batman #49 in 1948.
