Writer Pete McTighe spoke of his love of Doctor Who to the Sydney Morning Herald:
“It’s been with me my whole life, it’s defined my taste in everything, and it’s been the most important show in my life.” He describes his realized dream of writing for the show as “just ridiculous, and incredible, and impossible.”

“[Director Jennifer Perrott is] very collaborative, she’s a great visionary. I adored working with her.”
Jennifer Perrott also spoke the the Herald about the creative freedom granted to her on set:
“I had a lot more input than I ever dreamed that I would. Most of my ideas were embraced. I did have very bold ideas. I was just waiting for them to be shot down, because that’s sort of what you’re used to, but it was the opposite. Chris [Chibnall] just said, ‘love it, go for it’.”
“[Pete McTighe and I are] like brother and sister. I just adore him. We just had so much in common that we loved.”
Pete Mctighe spoke further of the episode he penned in Doctor Who Magazine issue 532:
“The story revolves around an intergalactic delivery company where something seems to be going wrong. This gives the Doctor a massive mystery to solve. Even though it’s set in the future, on the moon of an alien planet, I wanted the episode to feel very real. And I think it does. There’s a lot of correlation with how we live our lives today.”
“One particular action sequence in my episode was so ambitious… but what you see on screen is exactly what I wanted. It looks amazing.”
“[Julie Hesmondhalgh has] injected the character with a really quirky, loveable quality.”
