Daniel Radcliffe and Jon Hamm, who plays heartthrob Don Draper in Mad Men, have been signed up to appear together in a new TV medical drama.

The Sky Arts show, about Russian doctors after the First World War, will see the actors play the same character – with Daniel portraying a doctor in his younger years and Jon playing the medic in later life.

Hamm, who will narrate the tale, will also interact with his younger self – played by Daniel – during some of the scenes, reports The Sun.

A source told the paper: “This is a great role for Daniel and he’s pretty excited about the prospect of working with Jon.

“He’s a big Mad Men fan and feels he can learn a lot from Don. But Jon knows all about Daniel’s qualities, too, so he’ll also be doing some learning.”
