Oh man. It's like two people on the opposite ends of the HAWTTIE spectrum meeting in the middle!

In the immortal words of Hannah Montana, it's "the best of both worlds!"

Daniel Radcliffe and Jon Hamm have reportedly signed on to appear in a four-part drama series in the UK, which will focus on Russian doctors after the First World War.

And apparently, they'll be playing the SAME character - just at different ages!

A source explains: inneresting story, and they're both more than capable actors, so we're excited to see them take on this kind of role!

Can't wait to check it out!
