Enola Holmes 3 Trailer Drops: Millie Bobby Brown Faces Wedding Day Crisis as Sherlock Goes Missing

The third chapter of the Enola Holmes saga is officially here, with Netflix unveiling its first trailer on Wednesday.

Millie Bobby Brown returns as the titular sleuth alongside Louis Partridge, with Henry Cavill and Helena Bonham Carter reprising their roles. The streaming giant confirmed the film will premiere globally on July 1, 2026.

The footage teases a major development in Enola and Tewkesbury's relationship, with the latter popping the question. Yet the celebration takes a dark turn when Sherlock vanishes, forcing Enola to make an impossible decision on what should be her special day. Scenes show the detective in full bridal attire, grappling with the urgent need to locate her missing brother.

According to the official synopsis, the adventure transports Enola to Malta, where "personal and professional dreams collide on a case more tangled and treacherous than any she has faced before."

Brown shared insights into her character's evolution for this installment. "What I love about this chapter is that Enola is stepping into a version of herself that feels much more defined but still evolving," she explained. "She's built something for herself, which is amazing, but she's also questioning what she wants next, and I think that's something so many people can relate to."

The actress also reflected on her chemistry with Partridge, noting that their on-screen partnership has deepened through their years working together. "There's a comfort and an ease between us now that you can't really fake," Brown stated. "What's been really nice is getting to explore a more mature version of Enola and Tewkesbury's relationship. It's not just playful anymore, it has real weight to it."

Behind the scenes, Brown's real-life husband Jake Bongiovi is serving as an executive producer on the project.
