Did you know that if we had a nickel for every Doctor Who episode in which you have to pay the Company for the right to breathe, we’d have ten American cents? Which still wouldn’t be enough — even with Kate Orman’s help — to pay for today’s supply of Oxygen.

A clear inspiration for this episode, and for the opening scene in particular, is Alfonso Cuarón’s Gravity (2013), which was a film about George Clooney and Sandra Bullock tumbling through space while discussing their relationship or something. It was huge at the time but it seems to have vanished without a trace. So it goes.

Simon alludes to a rogue AI that turns the whole world into paperclips in a scenario known as the paperclip apocalypse. This isn’t a million miles away from the grey goo problem we identified three weeks ago in our episode on Smile — Episode 284: Happy to Be There.

The script for this episode is available from the Doctor Who script library on the BBC website. Quite a few scripts have been available online for a while, but a much larger number were made available on the BBC Writers page in February this year, thanks to RTD’s launch of the Whoniverse, we think.

Nathan’s recent podcast appearance was on Dave Rennie’s Doctor Who podcast A Kettle and Some String, in which they did a deep dive on The Waters of Mars.

At the end of the episode, when Nardole joins Bill and the Doctor in a hug, he signals his intention (delightfully), by saying ‘Cuddle’. The Blu-ray subtitles incorrectly render this as ‘Glad though. [Chuckles]’. Neither line is in Mathieson’s script.

Nathan is on Bluesky at @nathanbottomley.bsky.social and Kate is at @kateorman.bsky.social, while Simon is on X at @simonmoore72. The Flight Through Entirety theme was arranged by Cameron Lam.

You can follow Flight Through Entirety on Mastodon and Bluesky, as well as on X and Facebook. Our website is at flightthroughentirety.com. Please consider rating or reviewing us on Apple Podcasts, or we’ll send you out in this thunderstorm without a hat.

You can find links to all of the podcasts we’re involved in on our podcasts page. But here’s a summary of where we’re up to right now.

So check out the latest episode with our hot takes on the new versions of these beloved fan classics; we’ll be back with another hot take when the new Series 1 box set is released.

Last weekend, on Startling Barbara Bain, we faced what is perhaps the most memorable and terrifying episode of Space: 1999 ever with our usual mix of valour and prosecco. It’s Dragon’s Domain.

And finally there’s our Star Trek commentary podcast, Untitled Star Trek Project, featuring Nathan and friend-of-the-podcast Joe Ford. This week, they went back in time to watch the crew of Star Trek: Discovery start off their second season in the far, far future in Kobayashi Maru.
