This minute-long video for the Canadian Paralympic Committee (which went viral this week after being posted on Mashable) is an impressive cinematographic feat. Starring short-distance runner Alister McQueen, the ad illustrates the kind of dogged determination that paralympians need for their long and often difficult journeys to the Games. What else requires dogged determination? Making a really awesome ad all in one single take–which is exactly what BBDO Toronto, the communications agency that came up with the concept, did. There’s also a making-of video (see below) that reveals how director Mark Zibert, CGI artists and a huge crew pulled it all off. Bring on London 2012.
