About A Young Doctor's Notebook:

Jon Hamm and Daniel Radcliffe star in an extraordinary new series based on the memoirs of a Russian doctor working during the Russian Revolution.
Following on from its run on Sky Arts A Young Doctor’s Notebook, is a unique four-part comedy drama based on a collection of short stories by the celebrated Russian writer and playwright Mikhail Bulgakov.
Jon Hamm takes on the role of the older doctor, who has a series of bleakly comic exchanges with his younger self, played by Daniel Radcliffe.
Recounting from his notebooks, the Doctor considers his life and career as he tries to treat the patients of a village that is struggling to enter the modern age. Dealing not only with the superstitious and poorly educated patients but with his own inner demons, the doctor reveals doubts about his own competence and struggles with the immense burden of medical responsibility.
Mikhail Bulgalov is widely considered to be one of the finest Russian writers of all time. His allegorical and most famous novel The Master and Margarita has been called one of the masterpieces of the 20th century.
Daniel Radcliffe comments: "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".
