The pair will play the same doctor at different stages of his life in the four-part series, A Young Doctor’s Notebook, by Russian writer and playwright Mikhail Bulgakov. Hamm will play the older man, who has a series of “bleakly comic” exchanges with his younger self, played by Radcliffe. Based on a collection of short stories, ‘A Country Doctor's Notebook’, by Russian writer and playwright Mikhail Bulgakov. draws heavily from the author’s own experiences as a medical graduate on the eve of the Russian Revolution, Bulgakov describes a young doctor’s turbulent and often brutal introduction to his practice in the backward village of Muryovo. Using a sharply realistic and humorous style, Bulgakov reveals his doubts about his own competence and the immense burden of responsibility, as he deals with a superstitious and poorly educated people struggling to enter the modern age.
