There's nothing quite like circulating shots of Harry Potter and Don Draper sharing a bath to help publicise your new Sky Arts show.
Due to air early next month, the pair star in A Young Doctor's Notebook, which is "based on the short stories of Mikhail Bulgakov. The adaptation features Jon Hamm as an older doctor who has comic exchanges with Daniel Radcliffe, who plays his younger self."
Speaking about his role to Digital Spy, Hamm said: "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."
Radcliffe, meanwhile, got straight to the point, saying: "It was great, because you know you are the envy of every woman ever." However, he did have this to add of the Bulgakov's work: "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."
