Wait, if Jon Hamm is playing an older Daniel Radcliffe, isn’t there quite a height difference? Then again, we couldn’t tell how tall anyone was in the most recent Mission Impossible. 

“Daniel [Radcliffe] will star alongside Mad Men heart-throb Jon Hamm in the show, about Russian doctors after the First World War.” You don’t need Russians to play Russians because you can have Harry Potter play a young Jon Hamm. Everything about this is plausible.
