Details have now surfaced on Sebastian Stan‘s top secret Once Upon A Time role.
Executive producer Edward Kitsis believes that Stan is a perfect fit for the part, and says the episode will explore the origins of the famous Hatter, which will include a Once twist on the original tale:
“In that episode, we find out how the Mad Hatter became mad. The first difference you’ll notice is who the Mad Hatter was and his backstory. Then what Wonderland is and the changes of it is something we hope to explore also. We’re hoping this tells you the story of the Mad Hatter, but also will leave you with questions about Wonderland.”
“Hat Trick” airs March 25.
