Mad Men star Jon Hamm and Daniel Radcliffe will appear in a four-part drama based on the memoirs of a Russian doctor for Sky Arts.

Jon says he’s been watching Bridget Jones’s Diary ‘on a loop’ to perfect the English accent required for the role of the older doctor who has a series of bleakly comic exchanges with his younger self (played by Daniel).

Jon said: “I am thrilled to get the opportunity to work on such rich source material with such fantastically talented people whose work I greatly respect, and to continue the relationship with Sky, who have taken such good care of Mad Men since acquiring it….

“Clelia Mountford and Big Talk have been championing this project unabashedly and I share their great enthusiasm for bringing something original, dark, funny and moving to light. Also, I have been watching Bridget Jones’s Diary on infinite loop, and I think I’ve finally got this accent thing sorted…”

A Young Doctor’s Notebook will screen on Sky Arts in 2013 and is based on a collection of short stories by the celebrated Russian writer and playwright Mikhail Bulgakov.

Daniel added: “I have been an obsessive Bulgakov reader for a couple of years now so when the opportunity to become involved in this project came up, I could barely contain my excitement. The book is funny, grotesque and heartfelt in equal measure and I look forward to working with a great group of people to help bring it to life”.
