Keanu Reeves appears very exhausted and in pain while filming intense running scenes in the pouring rain for more than 10 hours straight with his pit bull costar by his side for the third installment of “John Wick” in Manhattan’s Times Square. Keanu was seen yawning several times and looked very tired as filming started 8pm Monday night and ended at 6am on Tuesday morning. At one point the pit bull ran away from the scene and started fighting with a horse which caused chaos on the set for a few minutes.
