It takes considerable nerve to drop a shark into the Seine and expect applause, yet Under Paris managed precisely that, and then some. Viewers arrived in droves, rewarding its 102 million views and hailing it as the most entertaining aquatic menace since Jaws. A grief-stricken scientist pursuing a freshwater-adapted beast through Paris, only for the affair to culminate in a city-drowning spectacle, proved quite hypnotic to the masses.

Audiences admired its energetic carnage, competent CGI, and a finale that moved with indecent speed, even earning a nod from Stephen King.

After two patient years, audiences may now turn their attention to Paris Under Water, which promises to continue the madness.

The sequel to Under Paris is steadily taking shape, seemingly having announced casting calls under the working title Paris Sous Les Eaux (Paris Under Water), although Netflix has yet to announce a confirmed release date. Current projections place Paris Under Water in a late 2026 window or beyond, reflecting a production timeline that has shifted more than once behind the scenes.

Bérénice Béjo, the lead actress of Under Paris, previously indicated a September 2025 filming start, though that schedule did not materialize, leaving the project in a prolonged script phase. Momentum returned when The Hollywood Reporter reported in February that Alexandre Aja was nearing a deal to direct the sequel. 

While plot specifics remain tightly guarded, Paris Under Water is expected to embrace the chaos left behind by its predecessor. The sequel reportedly shifts to a fully submerged Paris, transforming the city into a haunting aquatic landscape shaped by the catastrophic, flood-driven finale.

The threat itself appears to have evolved, with mutated sharks now implied to be spreading across major river cities worldwide, raising the scale from local disaster to global menace. Bérénice Béjo has hinted at a markedly different tone, suggesting a reinvention that still retains its central predator, alongside expectations of an exciting cast.

Casting details for Paris Under Water remain largely unconfirmed, yet a few familiar names continue to surface in industry reports while fans could sit back and wait for new additions in the cast. Bérénice Béjo is widely expected to return as Sophia Assalas, the grief-stricken marine biologist at the heart of the original film. Her character is now positioned to navigate a fully flooded Paris, confronting both personal loss and an evolved aquatic threat.

Nassim Lyes is also frequently cited as a likely returnee, reprising his role as Adil Faez, the resilient Seine police commander. His dynamic with Béjo provided emotional grounding previously, and a continuation of that partnership could anchor the sequel’s heightened stakes.

Behind the camera, Alexandre Aja’s involvement signals a stronger emphasis on survival-driven horror and visceral tension, given his experience with intense creature narratives like Crawl and Piranha 3D. With Vincent Roget ensuring continuity, Paris Under Water looks ready to live up to Under Paris's reputation as one of the year’s best Netflix movies, only on a grander scale
