As of my knowledge cutoff in September 2021, "John Wick: Chapter 4" has been announced and is currently in development. The fourth installment in the John Wick franchise was originally scheduled for release on May 21, 2021, but due to the COVID-19 pandemic, its production and release dates were delayed.
The plot details of "John Wick: Chapter 4" have been kept under wraps, and not much information has been revealed about the storyline. However, it is expected to continue the story of John Wick as he navigates the dangerous world of assassins and seeks revenge against his adversaries.
Keanu Reeves is set to reprise his role as John Wick, and Chad Stahelski is returning as the director. The film is also expected to feature a talented ensemble cast, including returning and new characters in the John Wick universe.
Fans of the franchise are eagerly anticipating the release of "John Wick: Chapter 4" to see more intense action sequences, high-stakes conflicts, and further exploration of the intriguing assassin underworld. However, for the most up-to-date information on the movie, I would recommend checking official sources or news outlets as my training data only goes up until September 2021, and the film may have undergone changes or updates since then.
