Following the resounding success of the first two films, Netflix has announced plans for Enola Holmes 3 which promises to continue the beloved teen detective movie series. Based on the series of novels by Nancy Springer, Enola Holmes, and its sequel, follow the teenage sister of Sherlock Holmes as the eponymous detective (Millie Bobby Brown) uses her sleuthing skills to crack cases that put even her famous brother to shame. Mixing fourth-wall-breaking humor and genuinely intriguing mystery plots, Enola Holmes was a perfect mid-pandemic release for Netflix in 2020.

Critics praised Brown’s performance, and the movie as a whole, pointing out its fun atmosphere and unique spin on Sir Arthur Conan Doyle’s Sherlock Holmes universe (via Rotten Tomatoes). The bulk of the cast returned for Enola Holmes 2 in 2022, and the sequel far exceeded expectations by being just as praised as its predecessor and topping Netflix’s viewership charts (via Media Play News). Another sequel seemed imminent, but it took until late 2023 for Netflix to offer promising updates on Enola Holmes 3.

Enola Holmes 3 Latest News

Millie Bobby Brown Offers A Production Update

Several months after the project landed a new director, the latest news comes in the form of a production update for Enola Holmes 3. The news was provided by Millie Bobby Brown, who announced that the threequel is due to begin filming soon. “I’m going to be doing an Enola Holmes 3 this year,” said Brown, “We start filming in the coming weeks. I’m very excited.” This means cameras should start rolling in March 2025, though a full production timeline is unknown for now. Unfortunately, it’s highly unlikely that Enola Holmes 3 hits Netflix before the end of 2025.

When asked to provide further details about the movie’s cast, Brown was quite coy. Perhaps the most curious mystery surrounding the threequel is whether Henry Cavill will return as Sherlock, and to that Brown merely said “You’ll have to wait and see.” Cavill has been a mainstay in the series thus far, but it’s unclear how his departure from Netflix’s The Witcher has changed his relationship with the streamer.

Enola Holmes 3 Is Confirmed

The Script Has Been Developing Since 2023

After a year of speculation, Netflix confirmed a script for Enola Holmes 3 was in development in late 2023. Scott Stuber serves as Netflix’s Head of Film, and he spoke glowingly of Millie Bobby Brown while labeling her as one of Netflix’s “homegrown stars” thanks to her turn as Eleven in the wildly popular Stranger Things. However, it would take another year for more news to surface when director Philip Barantini signed on to oversee the project.

In early March 2025, Millie Bobby Brown revealed that production was set to begin later that same month. This is the first major update on the project since 2024, and the first sign that the long-awaited threequel is finally getting off the ground. However, nothing is known about the show’s timeline, and there is currently no release window provided for Enola Holmes 3. Based on the usual timeline that a movie’s production follows, the next installment in the series won’t arrive before 2026.

Enola Holmes 3 Cast Details

Old Faces Should Return To Enrich The Narrative

While the full cast of Enola Holmes 3 has yet to to take shape, it stands to reason that Netflix will want to bring back the familiar faces from the first two. Most importantly, Netflix’s resident it-girl Millie Bobby Brown is already confirmed to return as Enola, since it is her star power that has anchored the franchise thus far. Likewise, Henry Cavill should also be on hand to play Enola’s older brother, Sherlock, while Helena Bonham Carter could return as the Holmes matriarch, Eudoria. Louis Partridge joined the fun in Enola Holmes 2 as Tewkesbury, and Enola’s beau should be back as well.

The cast of Enola Holmes 3 should include:

Actor	Enola Holmes Role
Millie Bobby Brown	Enola Holmes
Henry Cavill	Sherlock Holmes
Helena Bonham Carter	Eudoria Holmes
Louis Partridge	Tewkesbury

Enola Holmes 3 Story Details

The Movie Series is Following the Book Series With Some Changes

Except for major book changes in Enola Holmes 2, the stories of the movies have followed the book series linearly. Therefore, it is likely that Enola Holmes 3 will follow the plot of Springer’s third book, The Case of the Bizarre Bouquets. In the novel, Enola avoids being sent to finishing school in order to help locate Dr. John Watson, Sherlock’s close friend and ᴀssociate. Enola Holmes 3 will probably add a few additional flourishes and expand upon the hit YA novels.
