Prey Alone, a 15-minute live-action short directed by Stephen St. Leger & James Mather. Shot entirely against green screen, the short film sports 350 visual effects shots, all independantly produced by a few guys from Ireland.

It is quite inspiring how a small group of people could've achieved such high-level of production quality.
