Factual error: When the hackers are trying to steal the photo from the woman's laptop, they turn up the TV to distract her.

Factual error: Emily tells Stephanie they'll leave at 9 on Wednesday morning. Leaving from Connecticut on a private jet at 9 a.m., you have to account for at least 8-9 hours of flight time, plus the 6-hour time difference, which works against the travelers, not in their favor. So it's absurd that they arrive in the morning - it should be nighttime.

In actual fact, any private company must by law provide its accounts via the Companies House website, available to anyone to view and download.
