Millie Bobby Brown returns in the Enola Holmes 3 cast, and the film shifts to Malta with several new names added around her. The third installment brings back Henry Cavill, Helena Bonham Carter, Louis Partridge and Himesh Patel while widening the ensemble with Hattie Morahan, Jason Watkins, Sharon Duncan-Brewster and Joe Azzopardi.
Malta for Enola Holmes 3
Malta is the setting for the third film, a choice that pushes the franchise into a more specific historical frame rather than another generic detective backdrop. Philip Barantini said, "Enola is now grown-up, she’s about to get married, and there’s an opportunity to make the film a little bit more grown-up, a bit darker, more scary", which is the clearest signal that this chapter is aiming beyond the lighter tone of the earlier films.
Jack Thorne put the theme even more plainly: "... this third film is about her second name, about being a Holmes, and specifically about the notion of losing that name in getting married." That gives the casting news practical weight: the film is not just adding faces, it is pushing Enola toward a story built around identity, marriage and family inheritance.
Returning names, new roles
Brown, Cavill, Bonham Carter, Partridge and Patel form the returning core, which tells viewers the franchise is not rebooting itself for the third film. Hattie Morahan joins as Tewkesbury’s mum, Jason Watkins plays a British brigadier, Sharon Duncan-Brewster appears as Mira Troy, and Joe Azzopardi plays Maltese revolutionary Mikiel Mizzi.
That breakdown matters because the new arrivals are not being used as anonymous additions; they are tied to the film’s social and political world. The presence of Mikiel Mizzi also lines up with the story’s move toward a Maltese independence fighter, giving the ensemble more than a simple family-and-detective structure.
Sherlock, treasure, and empire
The plot framework reaches beyond Enola’s immediate circle, with Sherlock’s disappearance spilling into a conspiracy involving the British Empire, an old adversary, missing treasure and a Maltese independence fighter. Before this film, Lord Tewkesbury’s mum and dad once got hitched in Malta, so the location is being used as part of the franchise’s own internal history rather than as decoration.
Malta also places the action about 100 or so miles from Sicily, and that geography gives the setting a tighter Mediterranean shape than the usual London-bound mystery. The result is a third film that sounds less like a repeat and more like an expansion: same lead, same family, but a harder edge and a cast built to match it.
How the new cast members specifically fit into the plot of Enola Holmes 3 is only partly spelled out, but the film is already signaling a more adult chapter around Enola herself. For viewers, the useful takeaway is simple: the franchise is keeping its main ensemble intact while pushing into Malta with a larger supporting cast and a story built around marriage, identity and a broader political mystery.
