Video game style effects in Indiana Jones 4

Isn't it fascinating how movies are turning into video games (and vice versa):

"The whole film for us has been really big on particle simulation, which is creating an environment inside of a computer and telling the computer the rules of the world," said Helman, who also worked on two of the "Star Wars" films. "You give the computer this gravity, this mass, this amount of wind and see what happens."

That means instead of crafting movement for every vine and leaf that Indy & co. hammer through, visual effects artists were able to drag and drop virtual vegetation programmed to react to the vehicles' presence and actors' movements. It's an application that's long become de rigueur for video games, and come full circle to the big screen.
