Good Omens - The Blitz, London, 1941  (Behind the Scenes)

Excerpt from Syfy Wire interview with Good Omens costume designer, Claire Anderson - about the Blitz scene:

Aziraphale’s tartan necktie becomes a bow tie, and his penchant for wide lapels, a nod to his wings, continues, this time with a spear-point collar. Crowley, who comes to save Aziraphale once again, is dressed more formally, in a full double-breasted wool suit that must have been hard for David Tennant to wear in the South African heat. “The rest of the crew were in flip-flops and T-shirts, and David was in the suit, hat, and those big boots,” Anderson says, recalling the shoot.  “He had to be very physically active in that scene, and yet David didn’t complain about the heat or anything. He’s amazing.”

Excerpt from David Tennant Does a Podcast With Michael Sheen:

David: We have just come from a publicity photoshoot for Good Omens, which is a show we’re doing, during which we had to sort of dress up in clothes and have our photograph taken, kind of as ourselves.

Michael:  Yeah

David: I don’t think I’m talking out of school when I say that both of us find that… not our favorite part of the job of acting.

Michael:  No. We haven’t talked about this until now, so this is quite fun. [David laughs]  Can I ask you, am I the grumpiest person you’ve ever seen at a photoshoot, or have you seen grumpier people?

David: Oh no, I’ve seen grumpier

Michael: You have?

David: Yeah.  I don’t think you’re that grumpy. I think you’re an honest version of how I’m feeling

Michael: I wanted to kill everyone. Including myself

David: [Laughing]  That’s exactly what’s going on in my head, but because I could see how annoyed you were at times, it made me become sort of a performing monkey, going “No, everything’s great! Everything’s fine!”

Michael: I’m so sorry

David:  No!  Because you’re right!  It was excruciating

Michael:  I was aware at certain moments that I was totally leaving you to pick up the pieces. [David laughs]  I was just refusing to answer certain things. I was like a child, just not answering.  And you were very nicely, because you’re a lovely person, saying something just so that there wasn’t utter silence.

David: Usually I’m you in that situation

Michael: [Laughing] Are you really?

David: Exactly. That’s what I mean. I think we’re very similar about it. I’m asking you, as a means of therapy for myself, why is that bit of the job so excruciating?

Michael: Because it sort of strips away a lot of the stuff that allows us to feel better about ourselves. 

David:  Right

Michael: So it strips away all the pretense of artistry.  It’s just, “MONKEY F**KING PERFORM, MONKEY!!!”
