"Every once in a while we get a story at fxguide that indicates just how far and how fast the industry is moving. The post on Attila the Hun, directed by Gareth Edwards, is one of those stories. Edwards produced the 250 HD effects shots by himself in five months using After Effects and Photoshop. Averaging 2 shots a day, it was one man against the armies of Attila the Hun."
