When Ryan and Clark are playing basketball you can see a tractor near the guys. After some shots then the tractor moves for no apparent reason left and right about 1-2 meters.
When Lex comes over to Ryan Ryan closes the comic book but in the next scene it is open again.
In the closing scene, when Ryan hands his Warrior Angel comics to Clark, it is clearly visible for a moment that most of the "comics" are actually covers filled with newsprint.
Immediately following the commercial break away when Ryan is hiding from his step father behind the bowling pins, you can see two crew members on the right side of screen exiting down some stairs.
