No, said Aziraphale, it's ineffable.

Question: How was it preparing for a role to play an angel?

Michael Sheen: Well, you sort of can’t play an angel, you know, you kind of have to find little details to try and connect with. So I thought about, well, if I was on Earth for thousands of years what would I enjoy about that. And, well, Aziraphale is someone who really enjoyes quality when it comes to clothes and things, so even though Crowley just like makes up his clothes and he always looks fashionable, I wanted Aziraphale to look like he picked things up over the years. You know, so the nice waistcoat from the Victorian era or a nice jacket from the Edwardian era and he kept that. So that kind of built up the look of the character and I like the idea that he’s like a comfortable old sofa, but as a person.

And also thinking about, well, if he’s an angel then he’s love, you know, he just is a creature of love, so how does that affect his realionship with Crowley who’s supposed to be on the opposite side of. He just can’t help but love him as well at the same time.

So you sort of focus on those kinds of things rather than kind of label of angel.
