Good Omens 2: David Tennant On Donning Crowley's 'Slightly Too-Tight Trousers' Once More [Exclusive Interview]

Fans were full of ineffable delight when Amazon announced there would be a second season of "Good Omens," the series whose first installment was based on the beloved book by Neil Gaiman and Terry Pratchett, which Gaiman adapted for the small screen.

In season 2, Gaiman and his co-writer John Finnemore takes us beyond the pages of the original book and focuses on the millennia-lasting connection between the book-loving angel Aziraphale (Michael Sheen) and the demon Crowley (David Tennant), who cares more about saving humanity than he'd care to admit.

While fans are certainly eager to see more of Aziraphale and Crowley, actors Sheen and Tennant were also more than happy to reprise their roles. "It was very pleasing to slip back into those slightly too-tight trousers," Tennant joked to me about donning Crowley's wardrobe once more. I talked to him about "Good Omens 2" before the SAG-AFTRA strike, and we touched on how season 2 even came to be, what it was like to have Jon Hamm's amnesiac Gabriel throw a wrench into Crowley and Aziraphale's relationship, and — for a brief moment — about fan fiction.

'I think it's fair to say that Michael and I didn't need much persuading'

With the first season, there was the source material from the book, but season 2 is new territory. How did Neil [Gaiman] pitch season 2 to you, and when did he pitch it to you in the process?

It gradually came into focus over a couple of years, probably. I mean, from the initial idea that there might be more story to tell, which probably had its genesis way, way back as a sort of fantasy idea, really, where we were shooting [season] 1.

And then [season] 1 came out, and I think from that point, there was a slow realization that actually there might be more to come. Neil was clearly excited at the idea, and I think Amazon were keen to do it. And Michael and I were thrilled that we would get to return to [these] characters. We always thought it was a one-off. That was how it was pitched. That's what we were contracted for. When we started off on that journey, there was never a sense to go further, but what a treat that it was going to. And I think Neil would drop us little nuggets down the months and years, really.

Then there was a point, now when would it have been? I was in Romania filming "Around the World in 80 Days." Michael was, I can't remember where he was, but we had a Zoom call together where Neil read us the first scene, the opening scene, which is, if you've seen it, you'll know we meet a very youthful Crowley and Aziraphale, very much way back at the beginning of time. And Neil read that out to us over a Zoom call and then gave us a quick sketch of what the rest of the series was going to be. He told us some of the other writers that he was working with, and some of the early ideas, and he told us how it ended. That was all worked out, and it just felt delicious, really. I mean from that moment on, it just felt like it was always meant to be. It felt like it was such a perfectly formed idea. I think it's fair to say that Michael and I didn't need much persuading.

'It's a bit like The Odd Couple with a kid, or two supernaturals and a baby'

One thing I love about both seasons is that Aziraphale and Crowley are definitely an odd couple, but in "Good Omens 2," they're an odd couple who gets a toddler — at least in the first few episodes with Gabriel.

Yes, yes. That's a very good logline. Yes. The odd couple with a toddler.

I have a toddler, and some of the lines, I was like, "Is Neil in my house taking audio of my child?" Because you had the established dynamic with Michael for Crowley and Aziraphale in the first season, how did the dynamic change in those scenes with the two of you and with Gabriel when he's in that toddler state?

Well, I suppose it's Gabriel's very presence that changes it, isn't it? I mean, he's the grit in the oyster there, because I think they've just about managed to figure out a way of existing separately and together without their head offices ruling their lives. They're living with existence in the shadows on Earth and actually having probably quite a reasonable time. I mean, Crowley's living in the back of his car, which isn't ideal, but they're bumping along, and they can spend time together with less of the threat of being told off for it.

The absence of heaven and hell has actually been quite a good thing for them on the whole. So to have Gabriel revisiting is a bit of a disaster. Especially — I mean, he did try to discorporate Aziraphale and that Aziraphale was actually Crowley at the time, and that's not something Crowley's wanting to forgive. So to have Gabriel back in their midst and inexplicably amnesiac at the same time, it's not really what they needed and it's not helping them to keep their heads down. So it's brilliant in terms of setting these characters off on a new story and taking them to places they didn't imagine they would ever have to go. It's a fantastic device and like you say, yes, it's a bit like the odd couple with a kid, or two supernaturals and a baby, something like that. And I think that's the joy, isn't it? If there's characters that you know and love, you just want to spin them into a situation that they've not been in before and sit back and enjoy it.

'You get to design a period look and then add another 25% on top of it'

Another thing in season 2, and I'm going to keep this spoiler-free, but there are a lot of flashbacks to other points in time, which you got a little bit of in the first season. But I think we get more of it here, and one of the things with those flashbacks is that you, especially as Crowley, get to wear the most magnificent costumes. What was that like for you, to embody these clothes and portray Crowley through all those different points in time?

Who wouldn't get a kick out of being able to reimagine what that version of Crowley would've been? Because unlike Aziraphale, who tends to be a bit more conservative in the way that he addresses whatever period he's living through and in some ways sort of changes very little, Crowley leans into wherever he is and tries to find the zeitgeist of the moment and chew it up and spit it out a little bit. So from a design point of view, that's great fun. Obviously, Kate Carin, our costume designer, was allowed to run riot, because you get to design a period look and then add another 25% on top of it. And Stevie Smith, who designs my makeup on it, gets to find new ways of sticking facial hair on me. And it's hugely fun to play, and hugely fun for everyone to create.

And those little stories — the stories within the story — to get to see those characters at different points in their existence, it's a treat. It was always Michael and I's favorite bit of the first [season], that sequence — episode 3 where you saw them traipsing through history. And so it was delicious that there was more of that in season 2, and they're very much crafted at specific points in the story to illustrate an element of how Aziraphale and Crowley's relationship has developed over the millennia and why they are where they are now. So they're not just indulgences for us all. They're very specific plot points to tell.

'I mean, I've experienced some fanfic in my time'

I'm sure there's fanfic out there that's similar to what we see of Crowley and Aziraphale, and it's interesting to see the official version of it.

Yes. I mean, I've experienced some fanfic in my time. I think it's best, probably not for me [to read]. Sometimes you find yourself doing some very, very extraordinary things. So perhaps I'll leave that ....

No, I think that's wise on your part. And then for my last question, it just looks like you're having fun when you're playing Crowley —

I wouldn't want you to imagine anything other than very, very hard work. Very difficult, very dull, very boring. I'm never enjoying myself at all.

Yeah, no, of course not! But for Crowley, is there anything you do to get into that mindset?

It was interesting going back for series 2, because there's been quite a gap between filming 1 and 2, and I was a little bit concerned that the voice or the walk or whatever else it might be have slightly left me. But once I was staring at Michael Sheen's bleached white hair and his ... oh, I could be rude. I'm not going to be rude. So no, it all sort of seemed to come back fairly easily, to be honest. I felt, there's certainly, it's a very pleasing character to inhabit and all that full cynicism that he splashes around himself, which actually hides, I would say, a heart of gold, although Crowley would never admit that himself. It was very pleasing to slip back into those slightly too-tight trousers. It really was a pleasure. It was great fun.

All six episodes of "Good Omens 2" premiere on Prime Video on July 28, 2023.
