Freeman is convincing
I agree, although I kept expecting to hear his normal voice. He has certain mannerisms,, such as the way he moves , shrugs etc.
He walked past me in London about three or four years ago, his eyes fixed down the street, making no eye contact with anyone. When I told my wife, later on, I said that he looked exactly like Martin Freeman. She laughed and asked what did I expect, and I said that often when you see someone famous, they look something like what they do on screen, but dressed differently, or scruffier, different hair, whatever. Freeman, though, was wearing exactly what he seems to wear in every programme, with exactly the same hairstyle, and looking exactly as old as he always has. Until this series, of course, where he’s got grey stubble, and actually looks his age!
