Last month we had told you that Daniel Radcliffe and Jon Hamm were in talks to star in the same role (but in different time periods) of an upcoming British drama miniseries.

Now the deals are done.

Variety reports on the show, to be based on a Russian novel of the same name:

The pair feature in “A Young Doctor’s Notebook,” a four-part skein inspired by a collection of short stories by Russian writer and playwright Mikhail Bulgakov set during the Russian Revolution.

Hamm takes the role of the older doctor, who has a series of bleakly comic exchanges with his younger self, portrayed by Radcliffe.

The report also included comments from both stars:

Hamm said: “Big Talk has 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…”

Radcliffe 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.”

Do you think Hamm and Radcliffe look similar enough to play each other’s older and younger selves respectively?
