what it is, a viral video promoting what was in 2008 a new lego "indiana jones" video game from lucasarts> we wanted to find a way to broaden the audience. we tasked our agency to come up with some new ideas, something really different that would get people talking the next day. >> what's more different than a giant lego boulder chasing someone dressed like indiana jones down a hill in the middle of a major american city? but still, with 5 million lego bricks, that's got to be a little heavy. >> really heavy. and they are sort of moving it like it was nothing. i was like 5 million legos? >> so what about that 5 million number flashing at the end? >> we created a very big ball of legos that was, at its core, was a big foam ball. >> a foam ball with an outer shell of about 4,200 pieces of legos stuck to those familiar green panels. >> we used rubber cement and actually glued the little bricks to the plates and then the plates got glued to the styrofoam which made up the giant boulder. >> it was people coming in on the weekend from our office and from lucas and just sat around and ate pizza
