Sir Ian McKellen // If you want to understand human beings, what you have to understand is that we all act, we all play parts. Like…when you got up this morning you decided what you would wear – you decided not to put a suit on. But if you’d been going to an important reception you would have changed your costume... We are used to the idea of changing our clothes according to what we are doing. And we change our language. You might swear in one situation but never in another. You’re constantly presenting yourself in a way animals don’t do. A dog is always a dog. That’s why he’s so funny when you put him in different situations, he’s always himself. Human beings adapt.
