"I like to disappear into a role. I equate the success of it with a feeling of being chemically changed. That's the only way I can express it"

Chiwetel Ejiofor's quote speaks to the power of acting and the transformative result it can have on an actor. He expresses the idea that when he achieves success in a function, he feels as if he has been "chemically altered" in some method. This suggests that he has the ability to completely immerse himself in the character he is playing, and that the experience of playing the function is so powerful that it has an enduring effect on him. This quote also speaks to the concept that acting is more than simply a task or a craft; it is an art kind that can have an extensive effect on the actor. It is a method for an actor to explore various elements of themselves and to express themselves in a distinct and powerful method.
