The Associated Press reports that a 3D advertisement for DreamWork’s upcoming Monsters Vs Aliens will be aired during the Super Bowl. The 90-second sneak preview will have the largest audience of any 3D telecast, with Jeffery Katzenberg pegging it as “perhaps the biggest media-advertising event in history.” About 150 million pairs of 3D glasses will be given away at various Pepsi/SoBe Life Water displays around the country in preparation for the event, and a television ad promoting the sneak peak can be seen here. Monsters Vs Aliens opens in traditional as well as 3D-compatible theaters on March 27th, 2009.
