Character mistake: While in the sewing workshop, the teacher approaches and asks, 'What's the matter, Charlie?' but at this point he is still known as Peterson. It's not until later on in the film that he decides upon the name of Charles Bronson. (00:11:35)
Character mistake: Jeff mentions Mathias could have septicemia which he says is "a bacterial infection usually in the bone" However as a medical student he should know that septicemia means blood infection and has nothing to do with the bone.

Character mistake: There is a misspelling on the cover of the issue of Forbes magazine shown in the presentation about Stark's life. It reads "Tony Stark takes reigns at 21". The correct spelling of the word is "reins". Stark may "reign" at Stark Industries but he would take over the "reins" of the company.

Character mistake: McQuarry enters the subway at the 103rd Street station on the 1. He is transferring to the 2/3 at Chambers Street when Bose approaches him. However, it makes no sense to transfer here. As someone who knows New York, McQuarry would transfer to the 2/3 at 96th Street to benefit from the express ride to Chambers. (01:03:05)
Character mistake: Bud keeps calling Sarah "Ma'am." Sarah is a corporal. Corporals don't get called ma'am or sir in the US Army. Bud has been in the Army for seven months. No soldier would make this mistake after the third week of boot camp. Anytime you call an enlisted man or NCO sir, you are looking at about 20-50 push-ups or sit-ups to correct you. It's conditioned into you.
Character mistake: When Erickson is telling Strahm that he no longer has any jurisdiction over the Jigsaw case, he mentions that over a dozen dead bodies were recovered at the meat packing plant, including two cops.

In reality, she actually did give him one minute almost to the second. (00:06:58)
