Other mistake: When Sam and Tara first meet Gale outside, after Gale gets punched, pay attention to the multiple news crews behind her as they start arguing about Gale's book. Randomly, they go from paying attention and recording to suddenly all dispersing and packing up after the shot cuts to Sam and then back to Gale. This makes absolutely no sense. They're all involved in a very famous case; there's no reason every reporter there would suddenly start packing up in the five seconds they were offscreen.
Other mistake: Boyd calls an office in Rome, Inspector Lavazzi. Lavazzi is not in his office, so another officer, Valeria, answers the phone, saying a few lines in Italian (in the rest of the movie, she speaks English with Lavazzi). Shyann Yan is not a native speaker, which would be fine given her ethnicity, but she is also not a competent one. Surely, she is not competent enough to be an officer in Italy. (01:04:00)
Other mistake: All the websites, both in the address bar and the results of the search, have no top-level domain like .com or .org. Everything is just www.something instead of www.something.com. (00:10:30)
