(Cover) - EN Showbiz - Jon Hamm and Daniel Radcliffe are set to star in a new TV show together.

The pair have signed up to appear in the four-part drama to be broadcast on the Sky Arts channel in the UK. The series follows a group of Russian doctors after World War I.

Jon is best known for appearing as womaniser Don Draper in 60s advertising show Mad Men. This time round he will portray one of the medical professionals in his later years, while Daniel will play a younger version of the character.

"This is a great role for Daniel and he's pretty excited about the prospect of working with Jon," a source told British newspaper The Sun. "He's a big Mad Men fan and feels he can learn a lot from Don. But Jon knows all about Daniel's qualities, too, so he'll also be doing some learning."

Jon will reportedly narrate the series, which is believed to contain some dark humour.

In some of the episodes, Jon will be seen interacting with the Harry Potter actor.

The show will see the doctor character battle with self-esteem issues and doubt his ability to treat patients. (C) Cover Media
