BifBangPow wasted no time, did they?
Anyway, looks like it's safe to say Capaldi won't be doing anything radically different with his hair for this role. And since it'll be a Mego-style figure with removable clothes, a Malcolm Tucker action figure will be an easy conversion. Or a World War Z figure that's a million times better than any of the official ones.
You can preorder the figure now. But if you're a real fan, you did that already, right?
