Other mistake: The software the FBI agent is using to decrypt the "Stego-encrypted GIFs" says "ANOMALLIES FOUND; TRUE", with 2 Ls, and closes the report with a pretty worrisome "EXRTANEOUS POGRAM FOUND; TRUE." (00:32:30)
Other mistake: In the sequence in front of the embassy when Jezzie runs towards the police car as it escapes, in the background Morgan Freeman's stand-in 'surrender' to the Russians way before the real Morgan Freeman does it in a close-up. (00:58:50)
Other mistake: Mercusio tazes Jezzie and enters her apartment. Look at the wall clock; the time shown is 4:05, when Cross was barely at the Watergate Hotel at that time. (01:13:00)
Other mistake: Megan is kidnapped during the lunch break, and when Cross reaches the Rose residence, his friend from the FBI tells him about the forensics exams not netting any results. When he gets to the crime scene the day after, though, it's swarming with feds who are still doing things like checking the computer stations and even photographing the chalklines of the strangled woman, all sort of investigations that you'd expect to have happened already in the previous 24 hours or so.
