Corrected entry: At the end of the film, Hoffman reached for a saw to get out of the chains. Thing is, in the original Saw one of the saws used was broken and in Saw 2 the other saw was dropped next to the wall next to the pipes that ran up and down the wall. The saw that Hoffman was reaching for should not have been in the place that it was in.

Correction: Eric Matthews grabs the saw from the side of the wall at the start of Saw III, then discards it somewhere in the middle of the floor a few seconds later, which is where it stays until Saw 3D. The placement of the saw is correct.
