Netflix’s most ambitious sci-fi series is back in production, and the first glimpse from the set is exactly as cryptic as fans would hope. Filming on Season 3 of 3 Body Problem is officially underway, with new behind-the-scenes photos surfacing from Camber Sands beach in East Sussex, England. The images — provided by CLICK Media and News and first reported by What’s on Netflix on June 9 — show stars Jess Hong and Marlo Kelly filming what appear to be highly dramatic sequences on the breezy British coastline.

A UK Detour Before the Real Base of Operations
Here’s what makes this beach shoot particularly notable: the primary production home for both Season 2 and Season 3 has actually shifted to Budapest, Hungary. The show’s massive scale demands the kind of expansive soundstages and sweeping Eastern European landscapes that Hungary reliably delivers for productions of this size. Season 1 was largely a British production, shot across London and surrounding locations — but that model has changed significantly.
The Camber Sands shoot is a specific exception, not the rule. Once these UK sequences wrap, the bulk of filming will continue in Hungary as the story builds toward its conclusion.
What the Set Photos Actually Reveal
The contrast between the two characters spotted on location is immediately striking — and deliberate.
Jess Hong, who plays theoretical physicist Jin Cheng, appears in worn, mud-caked clothing that reads as historically vague and rough-edged. The visual strongly suggests Jin is back inside the San-Ti’s virtual reality simulation — the show’s most visually unpredictable storytelling space.
Marlo Kelly, playing human-alien liaison Tatiana Haas, cuts a sharply different figure in a sleek all-black tactical outfit with knee-high boots. The contrast is jarring enough on its own — but several photos also show Tatiana with a heavily bloodied right arm and hand, raising immediate questions about what she’s pursuing, and whether the lines between the virtual and the real have begun to collapse entirely.
A third key cast member was also spotted: Sea Shimooka, who plays the San-Ti’s AI avatar Sophon, appearing in her signature slicked-back all-black look — and holding what appears to be a green, gold-embossed book of fairy tales. For readers of Cixin Liu’s third novel Death’s End, that detail will land like a thunderclap.
The Final Chapter Takes Shape
The series — created by Game of Thrones veterans David Benioff and D.B. Weiss, alongside Alexander Woo — is adapting Liu’s sprawling Remembrance of Earth’s Past trilogy for Netflix. Season 3 represents the concluding chapter of that story, and the production team has confirmed they are filming precisely the number of episodes needed to bring the narrative to its natural endpoint — no filler, no padding.
Season 2 will also feature a reduced episode count compared to the debut season, a deliberate creative choice rather than a budget consideration.
Adding to the intrigue, four major new characters are being introduced as production scales up in Hungary. Casting announcements are expected to follow in the coming weeks.
Filming on Season 3 was always penciled in to begin in June 2026 — and these set photos confirm that timeline held. No premiere date has been announced yet, but the machine is clearly moving.
