American animator Glen Keane's "Duet" has recently been added to the running list of films shortlisted for the upcoming Academy Awards. Keane is known for his work with Disney. Since the late 1970s, he worked as a top character animator in a number of the company's films, including The Little Mermaid, Aladdin, Beauty and the Beast, Tarzan, and Tangled. However, it was truly when Keane left Disney to create his own studio when we start seeing the full capacity of the animator as an artist. For example, this entire short is hand-drawn, something of a lost art in a world that has taken so well to digital imagery and animation. It's incredibly impressive, and I'm sure you'll all love it too.
