Brian Cox is an Emmy-winning actor who has appeared in - oh, I don't know - about a million movies. Most of them after he turned 40. He's often the villain and usually larger-than-life. He played Agamemnon in Troy, the shrink in Running with Scissors, the principal in Rushmore - and in none of those did he get to speak with his native Scottish accent. He's now on Broadway in Tom Stoppard's Rock ?n' Roll.
