What’s the older movie about these troubled youth?

I was on this plane ride to africa and watched this movie about these troubled youth smoking cigarettes. And it started out with a school building and a guy with glasses talking. And then there was a scrap yard with a girl and I think the kids pretended that they were in the military wearing camo and Playing with pretend guns and I think I remember that the kids would film a movie with a video camera. And I think one of the kids liked the girl in the group.

How about Super 8 (2011)?
