Sheriff Decatur and @jimdklock met on set with Keanu Reeves, a big supporter of @specialolympics and he took time in between takes to sign T-shirts to show his support.

One of my absolute favorite parts of the acting profession is getting a chance to work with amazing people who jump at an opportunity to help others! So grateful to Keanu, @alexmorgan13 @armiehammer supporting the Special Olympics! #johnwick #keanureeves
