James Corden might be known Stateside as the Emmy-winning host of The Late Late Show and its acclaimed Carpool Karaoke segment, but he’s making his long-awaited return to UK comedy following his rise to fame as Smithy on Gavin and Stacey.

The 43-year-old TV host, actor and father-of-three is set to star in Mammals, a new six-part comedy drama from Jez Butterworth (Le Mans ‘66, Spectre) that also stars Oscar-nominated actress Sally Hawkins (Paddington, The Shape of Water).

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

Here, we reveal everything we know so far about Mammals, including the rumoured release date, the film’s plot, cast list, trailer and more.

What’s the release date of Mammals on Prime Video?

Mammals will be released exclusively on Prime Video later this year. Amazon has yet to confirm a specific release date, but we’ll update this article when we know more.

We do know that it will consist of six episodes.

Prime Video subscription required.

What’s the plot of Mammals? 

The plot for Mammals is being kept firmly under wraps, but the show’s writer Jez Butterworth offered the following clue: “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.”
