"It's odd because it doesn't look anything like me. And not because it's a wolf," joked Cumberbatch while promoting his role as wolf leader Classified in the forthcoming "Madagascar" spin-off "Penguins of Madagascar." "I could see bits of [myself in] Smaug cause I did lots of facial captures...so even being a dragon, despite being a biped mammal, I saw myself in that fire-breathing serpent of how many hundreds of years old...but yeah, being a wolf, it feels a little bit sometimes when I'm watching it like I'm dubbing someone else's performance."
Luckily for the "Sherlock" star, he didn't have to change up his natural speaking patterns too much for the role.
"I wanted to give him a sort of serious Englishness and pomposity," said Cumberbatch winkingly, "so yeah, I kept my voice for that."
