Corrected entry: At one point everyone is running in the woods. When they say "don't need no land, don't need no tree, out in the water that's where I wanna be," you can see the shadow of the helicopter that's shooting this scene.
Corrected entry: In the "swim records" scene, the records listed are impossible to achieve in any Coast Guard vessel, let alone swimming! (500 yard gear swim in 5.48 seconds...800 yards...10.63 seconds, etc etc). That would equate to about 200 mph roughly. That's some FAST swimming.
