I picked up Brief Interviews With Hideous Men at my local library based on the title alone, and thus began a long appreciation of Wallace's work. Sad news.
“How is it that I am a good actor? What I do is I... pretend to be the person I’m portraying. You’re confused. Case in point: in Lord of the Rings, Peter Jackson comes to me and says ‘I would like you to be Gandalf the Wizard,’ and I said ‘You are aware that I am not really a wizard?’ and Peter Jackson said ‘I would like you to use your acting skills to portray a wizard for the duration of the show.’ So I said ‘Okay’ and then I said to myself ‘Mmm.. How do I do that?’ And this is what I did: I imagined that I was a wizard, and then I pretended, and acted, in that way on the stage. How did I know what to say? The words were written down for me in a script. How did I know where to stand? People told me where to stand." -- Sir Ian McKellen, Extras
