Mad Men star Jon Hamm is set to test his British accent in a new TV mini-series alongside Daniel Radcliffe.

The actors will portray the same character in upcoming comedy drama A Young Doctor's Notebook, with Harry Potter star Radcliffe playing the lead in his younger years.

The show is inspired by a collection of short stories by Russian playwright Mikhail Bulgakov and is set during the Russian Revolution.

Filming is currently taking place in London, according to New York Post columnist Cindy Adams. (MT/PYN/KL)
