The MailOnline has the first photos of Keanu Reeves on the Brooklyn set of John WIck. The photos were taken yesterday while he was on set in Brooklyn shooting a scene with Williem Dafoe. His face was covered with cuts for the film.
You can view the article photos here.
Update: Moviepronews has 7 of the photos that are larger. Thanks to @JeanneStandal for tweeting the link!
