Since I posted I'll do some explaining. The gist of the Truman Show, and its been a few year so forgive errors, is that a media corporation decides to film the life of a person without his knowledge (manipulation for profit). To do this they create a fake world that he's lived in his entire life. He starts to get little clues that things are not as they seem. This short piece is the end of the movie where he tries to escape and hits the wall 'sky'. The media is the short shots inside the 'control room'. For me the shot of him touching the sky brings back of flood of emotional memories of my own discovery that the media has created this fake world. The hopeful end is his step into reality.
