The Amazon Original series - which Butterworth describes as a ‘relationship whodunit’ - will premiere exclusively on Prime Video later this year.

What’s the plot of Mammals? 

The plot for Mammals was confirmed by Amazon in October 2022. It reads as follows:

"Mammals follows the story of Jamie (James Corden), a chef whose world implodes when he discovers shocking secrets about his pregnant wife, Amandine (Melia Kreiling).

"Jamie finds himself hunting for answers with the help of his brother-in-law Jeff (Colin Morgan). Through this hunt, the cracks in Jeff’s marriage to Jamie’s sister Lue (Sally Hawkins) also widen. 

"In this darkly comedic drama, revelations and secrets come to light as the complexity of modern marriage and fidelity are exposed.

"In a world of eight billion, what happens after we've found 'the one'? Can we stay true to the promises we strive to keep when, after all, aren't we all just Mammals?"

The show’s writer Jez Butterworth previously offered the following clue to the series' plot: “A good marriage is the most magical thing. In a world of eight billion, you’ve found the one who gets you, ignites your body and soul. Who allows you to grow and flourish.

"Who gives you the spark, the confidence to become you. You’re also never going to have sex with anyone else, ever, and then you’re going to die, and be dead forever.”

In May 2022, Butterworth spoke at the Prime Video Presents UK showcase in London, and he explained why we know so little about the series.

"I'd love to be able to reveal more, but if I took you more than about six minutes into it, I would ruin the series. Everything that happens after the first six minutes is a spoiler," he said.

"It's a relationship comedy that doesn't really discuss relationships at any point. It's more like a whodunit, and I think most relationships do end up as crime scenes, don't they? So I guess if you like James's work and Sally's work then you should watch it."

Who’s in the cast of Mammals?

  • James Corden (The Late Late Show, Gavin & Stacey) plays Jamie Buckingham

  • Colin Morgan (Humans, Belfast) plays Jeff Wilson

  • Melia Kreiling (Filthy Rich, The Borgias) plays Amandine Buckingham

  • Sally Hawkins (Paddington, The Shape of Water) plays Lue

Henry Lloyd-Hughes (Killing Eve, The Inbetweeners) and Samuel Anderson (Witless, Doctor Who) also star.

Speaking about the show’s acclaimed cast, Butterworth said: “James Corden is the only 10-time Emmy winning chat show host to also win the Tony Award for Best Actor.

“His performance in One Man, Two Governors was like seeing Mickey Rooney, Terry-Thomas and The Marx Brothers rolled into one. His Smithy in Gavin and Stacey is for the ages - he took a needy, big-hearted mess of a supporting character and made it iconic. 

“But neither is a patch on his Sea Monster in The Late Late Show Shape of Water sketch with Sally Hawkins. Google it.”

He continued: “I am jubilant to be working with Sally again, and Colin Morgan too. Alongside the astonishingly talented Melia Kreiling (below), they make a team of world-class storytellers.”
