Netflix has confirmed that The Twin, the Jamie Dornan crime-noir formerly titled The Undertow, will now premiere on January 1, 2027. The six-part series had been expected in 2026 as part of the company’s Next on Netflix update.
The date is the real story
For Netflix UK, January 1 is a high-traffic date. Recent years have seen the slot go to Harlan Coben adaptations such as Fool Me Once and Stay Close. Placing The Twin there instead puts a less established title in one of the streamer’s most dependable launch windows.
That is not a neutral scheduling detail. It suggests Netflix is willing to let star-led IP and a recognisable format carry what media teams call a tentpole slot — a date reserved for titles expected to drive concentrated viewing around a new show — rather than defaulting to a single author’s franchise.
What the series brings
The drama stars Dornan as identical twins Adam and Lee, with Mackenzie Davis as Nicola. Netflix’s updated synopsis describes a loveless marriage, a tangled romantic past, and a split-second decision that pulls Nicola and Lee into a week of secrets; as the synopsis puts it, they are “living on borrowed time.”
Key facts for planners:
- New title: The Twin (formerly The Undertow)
- Release date: January 1, 2027, moved from a 2026 slot
- Format: six episodes
- Cast: Jamie Dornan, Mackenzie Davis, Iain de Caestecker, Gary Lewis
- Production: Complete Fiction and Wiip, based on a Nordisk Film Production series
Filming took place in May 2024 across the Scottish Highlands, Sutherland and the Isle of Mull. Dornan is best known to UK audiences for The Fall, a useful shorthand for the show’s psychological register. Davis recently appeared in Netflix’s horror series Below, giving the title a second streaming handle.
Why media planners should care
For anyone mapping next year’s streaming calendar, this is a concrete change. If a client’s campaign is built around Netflix’s early-January releases, The Twin replaces the usual Coben-shaped assumption. That means updating Q1 planning timelines now instead of waiting for the next slate confirmation.
The larger strategic test is whether a newer title can hold the New Year’s Day audience. If it does, Netflix may rotate more originals into that window rather than keeping it tied to one formula. That would shift how buyers think about seasonal inventory and adjacent categories.
Bottom line
The title changed, but the slot is the headline. Netflix is placing a swing title in a proven position; how it performs will show whether the platform’s most reliable January real estate is franchise-bound or up for grabs.
