Netflix Sets a Date to Introduce 'Legends'
From the series creator of 'Luther' comes a story based on the real-life UK customs officials who went undercover to fight the illegal drug trade.
Most of the time, when people refer to the “Butterfly Effect,” it’s in relation to stories about time travel. (Doctor Who recently even went as far as to have a character step on a butterfly, only to turn into a weird hybrid.) But the actual phrase comes from chaos theory and mathematician and meteorologist Edward Norton Lorenz, who meant it as commentary on the here and now, in relation to weather. (A butterfly flapping its wings influences the path of a tornado weeks later.)
I bring this up because Neil Forsyth’s transition to Netflix from the BBC for his newest series feels very much like a byproduct of the streaming service currents at play. Idris Elba wants to make more Luther – a show created and written by Forsyte. Netflix agrees to pay for it, and the movie, The Fallen Sun, becomes a direct-to-streaming success in 2023. Not a year later, in August 2024, Netflix announces it has greenlit the newest series from Forsyth, Legends, after his next series, The Gold, failed to perform on Paramount+ despite being a massive hit on the BBC.
A coincidence? Perhaps. But the result is that Forsyth’s latest six-part thriller series, based on a real-life heist, will debut on Netflix as a binge drop in May 2026, with a cast that’s good enough to overcome the handicap of being dumped all at once.
Here is the series’ synopsis:
Legends is inspired by real-life criminal investigations following a group of British Customs employees sent undercover to infiltrate some of the U.K.’s most dangerous criminal drug gangs. In the early ’90s, her Majesty’s Customs and Excise was losing its battle with illegal drug smuggling across Britain’s borders. The solution was extraordinary. In a top-secret operation, a small Customs employee team was sent undercover. Their task — to infiltrate Britain’s most dangerous drug gangs.
But these were not trained spies. They were normal men and women, plucked from ordinary lives around the UK, put through a basic training regime, and tasked with building new identities in the criminal underworld. These identities were called legends.
As befitting a show called Legends, the cast for this thing is absolutely stacked. The series ensemble stars Steve Coogan (Brian & Maggie), Jasmine Blackborow (Marie Antoinette), Tom Burke (War & Peace), Hayley Squires (The Miniaturist), Aml Ameen (I May Destroy You), and Charlotte Ritchie (Grantchester).
Other major names in the supporting cast include Tom Hughes (Victoria), Con O’Neill (Our Flag Means Death), Gerald Kyd (Ridley), Douglas Hodge (The Great), Johnny Harris (A Gentleman in Moscow), Paddy Rowan (Time), and Robbie O’Neill (Adolescence)*.
