Filming anything outdoors invites people to invade the shot and, most of the time, it's a distraction.
But sometimes that unknown person adds an even deeper factor to the video.
Musician Carlos Whittaker decided to film a music video for his song, "God of Second Chances," in a run-down area of Atlanta. The video was clearly designed to show that homeless people deserve another shot, especially considering a lot of them are simply down on their luck.
And then a homeless man, Denny, turned the video into something great. He sang right along with Carlos and his Bob Marley-esque tones added a whole new element.
