'Murrow is played in Good Night, And Good Luck by David Strathairn, that actor of precise inward silence. He has mastered the Murrow mannerisms, the sidelong glance from beneath lowered eyebrows, the way of sitting perfectly still and listening and watching others, the ironic underplayed wit, the unbending will.

'There are small moments of humour. After one broadcast fraught with potential hazards, Murrow waits until he's off the air and then there is the smallest possible movement of his mouth: Could that have been almost a smile? David Strathairn is a stealth actor, revealing Murrow's feelings almost in code.'
