Keanu Reeves, the star of ‘John Wick: Chapter 4,’ was so exhausted from working on the film that he wanted his character to be definitively killed at the end, according to franchise producer Basil Iwanyk. Reeves became physically and emotionally drained during the shooting process. However, there is still a possibility for another Wick chapter, as Reeves and director Chad Stahelski are discussing the story for a potential future film.
