Jon Hamm has said he fears being hammered for his English accent in his new TV drama.
The Mad Men star plays a doctor in pre-Revolutionary Russia in A Young Doctor's Notebook, on Sky Arts 1.
He told the Radio Times: "I have something approximating an English accent. I'm sure I will be eviscerated for my horrible attempt, but I am giving it a try."
Asked whether he was any good, he laughed: "I am very aware of Dick Van Dyke, but I hope I will be marginally better than that."
Dick Van Dyke played cockney chimney sweep Bert in classic musical film Mary Poppins, but his accent was derided as one of the worst in film history.
