Against all expectations, Keanu Reeves' neon-infused action franchise delivers its greatest film to date with John Wick: Chapter 4. But even though the magnificent set pieces leave us wanting more, it appears that the Baba Yaga bids adieu in John Wick: Chapter 4. Thankfully, Ballerina, a planned spinoff featuring Ana de Armas as Rooney, a killer who only makes a brief appearance in John Wick: Chapter 3 — Parabellum (where she was played by Unity Phelan), will carry on the series. Interestingly, though, Ballerina isn't mentioned specifically in John Wick: Chapter 4. Nevertheless, a few of the film's primary plot points serve to establish the eagerly awaited spinoff.
