John Wick was a surprise hit for Lionsgate earlier this year, scooping an impressive $78m at the worldwide box office from a budget of only $20m. A sequel was soon greenlit and Reeves has said that the film could be shot this month by director Chad Stahelski.

He also spoke about the narrative arc of the film, which looks set to explore the dark recesses of the central character’s past life as a brutal assassin. “I think we have a really good premise, and it’s an organic premise,” he said. “It’s basically — to me there’s John Wick and then there’s John. You know, John is the married guy whose wife just died, and that five years of his life, then there’s John Wick, who’s the mythical assassin. In this, John Wick’s past comes and infiltrates John’s life and John Wick, in a way, has to fight for John.”

Later in the interview, Reeves teased further depth being added to the criminal underworld of assassins at the centre of John Wick, including the Hotel Continental.

“Chad and the writer, Derek Kolstad, they’ve really listened to what people have enjoyed about the work and how they speak about it,” he said. “So there’s definitely that influence of the other world, the Continental world, the look, the feel, what it is about the movie, what made people like it; is definitely being paid attention to and the world opens up in this chapter.”
