Continuity mistake: The cut (s) on Jim's lower left lip frequently changed. At the "Wildcats" game, there appeared to be three slits, but they were not easily seen and it wasn't apparent how he got them. In the earlier beating he got from Lee's Heavy #1 and 2, his lip didn't get cut and the previous cut on his lip was not visible. When Jim met with Neville, he had three distinct vertical slits/cuts on his lower left lip. Thereafter, the appearance (presence or absence) of these cuts continued to vary. (01:25:55 - 01:31:45)
Continuity mistake: Amy set Jim's book perpendicular and very close to the desk's front edge and the pen was diagonal on the book's cover but not close to the desk's edge. When the book came back into view, the pen had been straightened and moved closer to the desk's front edge. (00:36:30)
Continuity mistake: A side view of the tennis court observation tower shows the umbrella angled around 45°, arched over Jim's head. A front view shows the umbrella behind Jim's back, more perpendicular to the ground. In the next rear view, his body is tilted toward the right, the umbrella is arched half-way over his head again, and his legs are no longer crossed. The next front view shows the umbrella in back of him again (more parallel to his upper body) and is fanned out backwards to not obstruct his face. (00:26:42)
Continuity mistake: Mr. Jones used his left hand to smack Jim across his right cheek/face. The injury Jim suffered (when it was even there) was on the left side of his face. The vertical slit (cut) on the left side of Jim's lower lip when he was in his office was not there (or too faint to be seen) when he was talking to Amy in the hallway. When Jim exited the building, the cut on his lip was obvious but the bruise on the left side of his face was more above his eyebrow than on the side of his left eye. (01:11:11 - 01:14:54)
Continuity mistake: In the empty (drained) swimming pool, there was a chair on its side with its back facing Jim. After Mr. Jones smacked Jim (but was not close enough to move the chair), the chair was on its back and at a different distance to the mat. (01:09:11 - 01:11:22)
Continuity mistake: The broom (?) handle that was sticking out of the pile of plastic was leaning into the corner of the empty swimming pool. At a more distant view (opposite end of the pool), it should have been visible but was not. In later views, the handle's position varied - straight up (not diagonal) and leaning in a different direction. (01:09:19 - 01:11:44)
