Millie Bobby Brown and Louis Partridge Team Up for a Cheeky Enola Holmes 3 Trailer Tease

Netflix just pulled the old teaser-for-a-trailer move for Enola Holmes 3, but at least they made it playful: Millie Bobby Brown and Louis Partridge popped up to solve a puzzle that reveals when the actual trailer drops. The pitch here is pretty clear too — Enola is heading into her most personal case yet, and yes, the big dangling question about her radical, vanishing mom is front and center. Fans have been waiting for that one since the first two movies blew up.

Trailer date, decoded

Netflix says the official Enola Holmes 3 trailer arrives on Wednesday, May 27, 2026. In the promo, Brown and Partridge work through a set of interactive riddles styled as a vintage newspaper to crack the date. It is part marketing gimmick, part scavenger hunt, and it does the job — the countdown is officially on.

How the teaser puzzle works

• They start with an envelope of clues and line it up over a faux old-timey paper to reveal hidden markers.
• Letters and numbers are tucked into the design — the letter 'M' is hidden in a chrysanthemum illustration, an 'A' is stitched into a vintage wedding gown, and a 'Y' appears when they align the envelope just right. Put together, that spells 'May' and leads you to the trailer date.

What this sets up for the sequel

The framing here is not subtle: the next movie is aiming straight at Enola's biggest personal loose end — where her revolutionary-minded mother disappeared to. After two hit outings, people have been asking for that answer loudly, and Netflix is clearly leaning into it with this little riddle campaign.

So, yes, it is a teaser for a trailer — but at least they let the stars play puzzle-solvers while we wait for May 27.
