Daniel Radcliffe and Jon Hamm return to Doctor's Notebook

Daniel Radcliffe and Jon Hamm are reuniting for a second series of TV drama A Young Doctor's Notebook.

The duo played younger and older versions of the same character in the four-part 2012 U.K. show, about a Russian doctor at different stages of his life, and based on the writings of Mikhail Bulgakov.

They will team up again for another season, and Radcliffe can't wait to get back into character.

He says, "I had absolutely no hesitation in agreeing to do a second series of A Young Doctor's Notebook. I had an incredible time working with the multi-talented Jon Hamm and of course am a huge fan of Mikhail Bulgakov's work and so was thrilled when I was told a second series had been commissioned."

Hamm adds, "I'm thrilled to come back to our wonderful, weird, wild world of A Young Doctor's Notebook. Series one was an absolute blast to work on and I'm looking forward to continuing this bizarre adventure."

The second season will air on Britain's Sky Arts channel later this year (13).
