John Wick is a super stylish assassin genre tale of redemption and revenge, in which the titular character hunts down the gangsters who killed his beloved dog, a final gift from his dying wife. Keanu trained extensively for months prior to filming the many fight scenes and was so dedicated to the shoot that he filmed the nightclub fight sequence with flu and a 40 degree fever. He also championed co-directors(and former stunt men) David Leitch and Chad Stahelski to take the directorial reigns for the project after working on several films together, including The Matrix trilogy, Constantine, Man of Tai Chi and more.
