The movie won't hit theaters until March 2023, but that didn't stop Keanu Reeves from swinging by Comic-Con to introduce a sneak peek teaser for John Wick Chapter 4, simply titled John Wick (which might be confusing given that this is also the title of the original film that launched the whole franchise). According to Deadline Hollywood, Reeves crashed the Collider's Directors on Directing panel, which included John Wick: Chapter 4 director Chad Stahelski as a panelist.

(Spoilers for the first three films in the franchise below.)

As I've written previously, for the benefit of those who missed the first three movies, John Wick (Reeves) is a legendary hitman (known as the Boogeyman or "Baba Yaga") who tried to retire when he fell in love and got married. Unfortunately, he's drawn back into the dark underground world by an act of senseless violence after his wife's death. Nothing will stop John Wick from seeking retribution. The first John Wick grossed more than $88 million worldwide for a film that cost around $30 million to make, and it was praised for its brisk pace, heart-stopping action sequences, and stylish noir feel.

So naturally, there was a sequel. In John Wick: Chapter Two, Wick takes on a whole slew of Russian baddies but finds himself honor-bound (per the professional hitman's code) to go on one last assignment. Of course he succeeds—he's John Wick—but the client, Italian crime lord Santino D'Antonio (Riccardo Scamarcio), tries to cover his tracks by posting a bounty on Wick's head. Wick ends up killing Santino—newly named to the High Table—inside the Continental Hotel in New York, which is supposed to be a safe space for assassins, and is declared "excommunicato," cutting him off from all the resources the hitman underground usually provides.
