A long interview with Steve Coogan in The Independent today:

Murray, says Coogan, is “recklessly truthful” and “heroically flawed”, the sort of well-intended but slightly damaged character that he relishes.

I am pretty happy with his characterisation of me and of Murder in Samarkand. I trust Steve and Michael, and I think they have got the message the film needs to convey. If it can be conveyed with humour, all the better. I am really starting to look forward to the filming now. We are just about at the point where production work will really take off, as filming on Genova is almost finished.
