When I first read the premise of The Diamond Heist, I thought, “Surely this can’t be real?” But trust me — it is. This Netflix mini-series dives headfirst into one of the most outrageous attempted robberies in British history. We're talking about a gang who planned to smash into the Millennium Dome in broad daylight with a bulldozer and vanish down the Thames in a speedboat — Mission: Impossible style, but very much set in Greenwich.
It’s a slick, three-part documentary that left me both gobsmacked and oddly admiring of the sheer audacity. The pacing is tight, the visuals atmospheric, and the storytelling almost too thrilling to believe — except it’s all true.
Plot Overview (No Spoilers, Promise)
Directed and written by Jesse Vile, the series unpacks the real-life 2000 attempt to steal the Millennium Star, a 203-carat diamond housed at the Dome. Through candid interviews with ex-criminals and retired officers, along with sharp re-enactments and rare archival footage, we’re pulled into a tangled world of surveillance, secret cameras, and criminals who truly believed they could pull it off. The plan? Ram through the Dome’s walls and escape with £350 million in jewels. What actually happened — well, I won’t ruin that.

Direction That Doesn’t Preach, Just Pierces
Jesse Vile does a smashing job of presenting both sides without romanticising the criminals or villainising the police. You feel the rising tension from the cops’ hidden camera vans just as much as you do from the gang’s bunker-like meeting rooms. It’s the kind of documentary that refuses to shout its message — instead, it lets the insanity of the plot do the talking. And oh, it talks.
Real People, Real Stakes
What really hits is the cast of interviewees. Luke Philpott (as Lee Wenham) and Tuncay Gunes (as Ray Betson) give dramatic weight to the story through reconstructions, but it’s the real players — Beth Wenham (Lee’s daughter) and police surveillance veterans — who provide the emotional core. You start to see not just the crime, but the families and futures hanging in the balance.
Cinematic Grit Meets Journalistic Precision
Visually, it’s impressive. Cinematographer Tim Cragg captures both the gloom of covert police operations and the cold flash of diamonds behind glass. The editing by Tom Dixon-Spain keeps everything propulsive, bouncing between suspenseful stakeouts and jaw-dropping confessionals. It's got a noir tint without feeling over-styled.

Audience Reactions: USA vs. UK
Here’s where it gets even more fascinating: British viewers see this as gritty, almost nostalgic true crime. It's local lore turned Netflix-worthy, and many UK critics praised it for its accurate portrayal of late '90s London. Meanwhile, US audiences are treating it like a James Bond prequel — thrilled by the brazenness, but often unaware this actually happened.
It’s proof that tone and familiarity change everything. What feels like “yep, we remember that” to a Londoner might feel like Oceans Eleven: East End Edition to someone in Ohio.
Final Verdict
With a 7.0/10 rating on IMDb (as of May 2025), The Diamond Heist is a razor-sharp blend of documentary tension and criminal absurdity. It's gripping, it’s occasionally funny, and it’s utterly British in its delivery—think Line of Duty meets The Great British Blag. If you love stories where truth outdoes fiction, this one’s for you.
