Mission: Impossible 6 Casts Sherlock Actress Sian Brooke

After a recent riveting villainous performance on Sherlock, Sian Brooke has nabbed a key role in Mission: Impossible 6.

While the stealthy, laser-grid-dodging op that is Mission: Impossible 6 will likely bring back returning franchise favorites opposite star Tom Cruise, it’s also corralling an impressive array of newcomers. Shortly after a social media exchange with director Christopher McQuarrie locked in Superman actor Henry Cavill, the six-quel now adds an actress who played the antagonistic centerpiece of the recent season of the BBC’s hit series Sherlock.

According to Variety, Mission: Impossible 6 has cast Sian Brooke for what will reportedly be “a key role” in the film. While details about Brooke’s character were not disclosed, the blockbuster sequel – the highest profile project of her career – comes in the aftermath of her shocking turn as Eurus Holmes on Season 4 of Sherlock. The character – initially introduced in other forms in disguise – was ultimately revealed to be the consciously-forgotten institutionalized younger sister of Benedict Cumberbatch’s Sherlock Holmes. Wielding a frightening genius-level intellect, Eurus channeled some sisterly enmity toward Sherlock with intricately sadistic machinations. Consequently, it’s quite feasible that she’s being sized up for a villainess role in Mission: Impossible 6.

Relevantly, the English actress Brooke fielded the Sherlock role shortly after appearing on stage (and a subsequent TV movie,) in a celebrated production of Shakespeare’s Hamlet, playing the madness-afflicted love interest Ophelia opposite Cumberbatch’s starring role as the revenge-fueled Danish prince. It’s a casting that also contrasts with the royal gravitas to be brought by the franchise’s other major female newcomer in Vanessa Kirby (The Crown, Everest). Additionally, Mission: Impossible: Rogue Nation standout Rebecca Ferguson will be back onboard as femme fatale Isla Faust, with franchise regulars Simon Pegg and Jeremy Renner also likely to return, though not quite confirmed.

Mission: Impossible 6 will have peeled away the proverbial mask hiding its true title by the time the film hits theaters on July 27, 2018.
