What is this new show with the gorgeous Don Draper and Harry Potter?

I fleetingly saw a huge poster when I was on the bus this morning. Does anyone know what it is?

Is it the young doctors notebook, on sky arts?

i know thats got potter in, not sure about other bloke.

Just googled it - it looks just my thing but as I'm abroad and don't have sky I'm going to have a long wait

Tom is right, I just passed a big poster as well. Starts in December on Sky Arts 1.
