The Hangover may have snagged Avatar‘s slot on the American Film Institute’s list of the top 10 films of the year, but James Cameron’s smash has found its way onto AFI’s companion list of eight “moments of signifcance,” alongside Jay Leno’s move to 10pm, the rise of Twitter, and Michael Jackson’s death. “James Cameron’s pioneering effort to unleash the human imagination was fully realized in 2009 with the release of Avatar, a film that firmly established itself as a landmark in the way stories are told,” the AFI citation reads in part. “[W]ith Cameron’s advances in CGI (computer-generated images) and 3D, Avatar enters AFI’s almanac as an achievement that will have profound effects on the future of the art form.” Just not as profound, apparently, as The Hangover.
