This powerful movie stars Sean Penn, Tim Robbins and Kevin Bacon. The trio have intertwined lives in the lower class suburbs of Boston. What mistakes can you spot?

There are a few problems with the "young kid" scenes that were shot in the early 70s. There's a sign for "no trucks" that wasn't used until the 80s. There's a modern day license plate on the fake cop car. There's also a modern day cop car in the background behind the 2 remaining boys as the 3rd one is taken away.

The concrete slab they write their name in is pretty magical - Dave doesn't finish the A when he's young, but the A is finished when they are older.

Katie isn't very good at being dead. You can see her breathing, and at one point her eye twitches.

Dave and Celeste have a discussion while he watches Vampire$. The movie doesn't "play" during the scene though - it jumps around from spot to spot.
