Factual error: Mozzy plugs a laptop into a PBX switch in what can be assumed to be a server room. Somehow, this remarkably grants immediate access to security cameras and elevator controls without so much as an internal IP address or any administrator login access. This is ridiculously erroneous as no security camera or elevator control would even be accessible from a PBX data line, as these are only able to pass voice/phone data and nothing more. (00:27:40)
Character mistake: When talking to Felix at the planetarium, he correctly states that Tycho Brahe's birthday is December 14, 1546. Later inside the planetarium, Felix says they are looking at the sky on Tycho's birthday, but then says in 1592. (00:18:20 - 00:19:05)
Character mistake: If you look at the piece of paper Neil takes from Agent Matthews the word "warrant" is misspelled as "warreant". (00:21:20)

Continuity mistake: When Sarah has been looking at Neil's laptop, the order of the books she places on top changes from when she first sorts them to when Neil pushes them off. (00:03:00 - 00:04:00)
Factual error: Neil and Mozzi are trying to date an image of the Chrysler building painting. In the process Neil tells Mozzi to scratch off a bit of titanium white paint from the Rembrandt. Titanium white wasn't discovered and made available for artists until 1921.
