'Hannibal season 3' trailer released
Richard Armitage plays the serial killer known as The Tooth Fairy in the NBC drama, which returns to TV next month, reported Digital Spy.
"I didn't know about him until I received the information from everyone else, who gasped and said, 'Oh, you're playing the Red Dragon', and I sort of said, 'I don't really know what it means'," Armitage says in the promo.
"And then I went in search of the book and found out what it really meant."
The trailer also provides rather spoilery glimpses at Hannibal Lecter (Mads Mikkelsen) and Bedelia du Maurier (Gillian Anderson) in Europe.
