I won't lie, this animated short film is so heartwarming and beautiful that it made me choke up. The movie is called "Duet," and it was created by Disney animator Glen Keane, who worked on some of Disney's great classics such as The Little Mermaid, Beauty and the Beast, Tarzan, Aladdin, and more. He left Disney in 2012, but is still producing amazing work, as you'll see here.
The movie was produced through Google's Advanced Technology and Projects group. There's absolutely no dialogue, but it has a wonderful soundtrack and tells a moving story which follows the lives of a man and a woman as they journey into adulthood and manage to find one another along the way.
