The two brothers play best friends on Amazon Prime show.

Below, the brothers talk of Ireland andnotpooping into a bag.

Domhnall had been working with Michael Moloney, our co-writer, on different things.

Frank of Ireland

We got in a room and started chatting and it happened organically out of that.

Brian, you play the titular Frank.

Is that okay?DG:That is what I was hoping for.

Take it away Brian.

I’m not even recording this part.DG:Good, good, good, as requested.

Sorry, Brian, do go on.BG:Okay, let me have a crack at this.

Frank, we thought of as a teenage boy with a temper basically.

Maybe we were reaching back into our own childhoods in some sense.

The whole story’s about him trying and failing to move on, I suppose.

Domhnall, tell us about Doofus.DG:Doofus looks up to Frank.

Like, the guys in Oasis were cool, and your older cousins were exactly as cool as that.

That’s the way Doofus sees Frank.

But it’s a relationship that is probably holding them both back.

But he’s a very sweet-tempered guy, for the most part.

The show references films, includingTaxi Driver,Memento, and12 Angry Men.

Is there anything in the show which is taken directly from your lives?DG:No.

Happily, I think everything’s basically made-up.

But I think there’s a level of looking at yourself.

I mean, everyone thinks that their life is a struggle.

So, there are elements of the world that are familiar but not the characters hopefully.

One that definitely isn’t true is pooping into a bag and presenting it to a man.

That didn’t happen.

How do you plan on winding this up?DG:[Laughs] It’s funny.

It only really struck me afterward.

So that’s where the name had originally come from.

It was like holy hell, how did I not see that before?

I don’t know.

I’m open to any offers with anything to do with the name Frank, basically.

It was utterly bizarre and we laughed a huge amount.
