Netflix released the full trailer for ‘Enola Holmes 3’ on June 10. The film is set to begin streaming globally on July 1, 2026. It is the third installment in the franchise starring Millie Bobby Brown, and marks the most structurally ambitious entry yet, in terms of both plot and production choices.
The trailer runs at a brisk pace and wastes no time. It opens with Enola seemingly settled into domestic happiness. Lord Tewkesbury, played by Louis Partridge, proposes to her. She accepts. Within moments, Dr. John Watson, played by Himesh Patel, runs her carriage off the road to deliver devastating news: Sherlock Holmes has been kidnapped.
The wedding is off. A rescue mission begins.
What the trailer shows
The official synopsis from Netflix reads: “Adventure chases detective Enola Holmes to Malta, where personal and professional dreams collide on a case more tangled and treacherous than any she has faced before.”
The trailer confirms several things. The case takes Enola to the Mediterranean island of Malta, a first for the franchise, which had previously been set almost entirely in Victorian England. Visually, the trailer shows sun-bleached stone architecture and narrow streets. This is a clear visual departure from the fog and cobblestones of London.

One sequence draws immediate attention: Enola stands on top of a moving carriage, in a wedding dress, holding a gun. It is a single shot that manages to summarise the film’s entire tonal tension. She is caught between a personal life she has chosen and a professional identity she cannot abandon.
The central emotional conflict is spelled out directly in the trailer. Enola asks the question: “Can I love him without losing myself?” This is not a new theme for the franchise, but the third film appears to sharpen it. The fear is no longer about whether she can find love. It is about whether love will cost her the thing she has worked hardest to build; her independence and her name.
Full cast
The returning cast is substantial. Henry Cavill is back as Sherlock Holmes, though in a reduced capacity given that his character is, quite literally, absent for a portion of the story. Helena Bonham Carter returns as Enola’s eccentric mother, Eudoria Holmes. Sharon Duncan-Brewster reprises her role as Moriarty. Himesh Patel joins as Dr. John Watson, a new addition to the franchise’s main ensemble.
The film runs 105 minutes and carries a PG-13 rating from Netflix.
A new director takes the wheel
This is the first ‘Enola Holmes’ film not directed by Harry Bradbeer, who helmed both the 2020 original and the 2022 sequel. Philip Barantini takes over for the third film. His appointment was confirmed by Deadline in November 2024.
Barantini is popular for ‘Boiling Point’ (2021), single-take thriller, more recently for ‘Adolescence’ (2025), Netflix limited series that drew widespread critical attention. His filmography is defined by controlled pressure and confined tension.
Barantini himself has compared the third film to ‘Harry Potter and the Prisoner of Azkaban’ in terms of franchise maturation. That is a bold claim to make publicly, but it signals a clear intention: the film is designed to take the series into darker, more adult territory without abandoning its core audience.
Jack Thorne, who wrote both previous films and also collaborated with Barantini on ‘Adolescence’, returns as screenwriter. That existing working relationship between director and writer is worth noting. ‘Adolescence’ was widely praised for its tight construction. If that collaboration carries over, the third film has a stronger creative foundation than the trailer alone can convey.
Production timeline
Principal photography began on April 10, 2025, in the United Kingdom. Filming moved to Malta, specifically to Valletta and Mdina, before wrapping on June 27, 2025. Barantini confirmed the wrap on Instagram. The shoot lasted approximately two and a half months.
Millie Bobby Brown began production on ‘Enola Holmes 3’ after completing her work on ‘Stranger Things’ Season 5, Netflix’s long-running sci-fi series. Brown also serves as a producer on the film through her production company, PCMA Productions, alongside producers Mary Parent, Alex Garcia, Ali Mendes, and Joshua Grode for Legendary Entertainment.
Cinematographer Matthew Lewis, who worked with Barantini on ‘Boiling Point’, also returns for this film. Aaron May and David Ridley composed the score, replacing Daniel Pemberton who scored the first two films.
Franchise numbers provide context
The first ‘Enola Holmes’ (2020) recorded 189.90 million hours watched in its first 28 days on Netflix. For a period in 2023, it appeared on Netflix’s list of most-watched films of all time. The second film, released in November 2022, reached 158.03 million hours in the same window and appeared in the global top 10 for four consecutive weeks.
Netflix formally confirmed the third film’s July 1, 2026 release date during its “Next on Netflix 2026” slate reveal in January 2026, positioning it as a major summer title.
Critical analysis: What the trailer signals
The trailer is confident in what it is showing, but careful about what it is withholding. The Sherlock kidnapping plot functions as a MacGuffin, a device to move Enola into action, not necessarily the thematic core of the film. The real story appears to be about identity and marriage, themes the franchise has circled since its first entry.
Barantini’s arrival changes the franchise’s creative DNA in ways that go beyond tone. His background is in single-location, high-pressure storytelling. Malta as a setting may allow him to create a version of that contained-world tension on a larger canvas. The question is whether his naturalistic, pressure-cooker style will work within a franchise that built its audience on charm and period whimsy.
The shift in the marketing is also notable. Previous trailers emphasised Enola’s detective work and independence. This trailer leads with the romance. That is a deliberate choice that may reflect both the story’s structure and a commercial calculation: Enola and Tewkesbury’s relationship has a devoted fanbase, and leading with the wedding brings those viewers in immediately.
The wedding-dress-and-gun image from the trailer is doing heavy lifting. Whether the film earns that image in its full context, or whether it becomes a piece of marketing that oversells the stakes, we will have to see.
The ‘Prisoner of Azkaban’ comparison Barantini made is worth scrutinising. Alfonso Cuarón’s ‘Azkaban’ succeeded in part because it genuinely changed the visual grammar of the franchise, not just the tone. Whether Barantini does the same with ‘Enola Holmes 3’, or simply delivers a competent, slightly darker sequel, is the central question going into release.
