An actor prepares
People often ask me how I prepare for a new part and I find this a really difficult question. An actor needs to know a lot about different sorts of people and different types of personalities. Imagine you have to play the part of someone who is ambitious and intolerant. Perhaps you aren’t like this but you must understand how people feel and behave when they are. So, I watch people all the time, especially when I’m preparing for a new part.
For me, when I’m acting, the costume is also very important. Clothes are really important to all of us. They tell other people a lot about who we are and who we aren’t. Different clothes can change our behaviour. Think about it. When you put on party clothes, work clothes or sports clothes you change a little. For example, in smart, expensive clothes you look good, you feel good and you are more confident. That’s why costume is important for me when I’m acting. If I put on the clothes of an old, poor homeless woman I feel more like her. The moment I put on the costume I change, and for a short time I am another person.
