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

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.
