I'm definitely one of those actresses who comes to a set knowing how I want to do a scene, and I definitely love input from my directors and my writers. I know that there's some actors who like to be left alone, they like to be very independent, but I actually really enjoy the teamwork.
It is the lone worker who makes the first advance in a subject; the details may be worked out by a team, but the prime idea is due to enterprise, thought, and perception of an individual.
