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: When John is watching the video of Cecilia on her website, the video progress bar we've seen twice makes no sense. The first time we see it, it's moving far too fast for the length of the video. Later, we see it a second time, and it has seemingly reset back to the beginning despite it being the same video, and again, it's moving way too fast.
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)
