"Acting is not being emotional, but being able to express emotion"

This quote by Robert Quillen speaks with the concept that acting is not about being psychological, however rather about having the ability to express feeling. This indicates that an actor must have the ability to depict a variety of feelings, even if they are not personally feeling them. It is not enough to merely be emotional, but rather the actor must have the ability to convey those emotions to the audience. This requires a particular level of ability and understanding of the craft of acting. It is insufficient to simply feel the feeling, but rather the star needs to be able to express it in a manner that is credible and engaging. This quote speaks with the idea that acting is not practically being emotional, but rather about having the ability to reveal emotion in a manner that is believable and interesting.
