The screen magnifies everything, even the way you are thinking.
I've been using narcotics for 20 years.
I never drink... wine.
It took me years to live down Dracula and convince the film producers that I would play almost any other type of role.
A screen actor is compensated in the knowledge that millions will see his performance at one time, where only hundreds will see it on the stage.
Of all the roles I've done on the stage, I'm partial to Cyrano de Bergerac.
