Why is it that English, drama and music teachers are most often recalled as our mentors and inspirations? Maybe because artists are rarely members of the popular crowd.
From a dramatic viewpoint, there are few professions that grant their members entry into other lives, high among them cops, doctors, clergymen, journalists and prostitutes. Perhaps that explains why they figure in so much television and cinema. Their lives are lived in the midst of human drama.
It's like the high school production of something you saw at Steppenwolf, with the most gifted students in drama class playing the John Malkovich and Joan Allen roles.
