"Even though I speak English, I had a dialect coach (Joel Goldes). I had long sessions with him during the entire filming of 24, and he was of great help to me as far as figuring out how my character would speak. Because Hassan was educated in Britain, we gave him a bit of a British accent. So in 24 you’ll find a complete change in the way I talk and in my voice quality as compared to what I’ve done before."
"Of special note is Joel Goldes’ vocal coaching: the accents are intelligible without being distracting."
