When Tyler is using the computer to get Marina's information, on the Patient Records screen he puts "Marina" as the last name and "Nedifar" as the first name.
When Laura and her friends are looking at Marina's profile page, her privacy for posts is set to friends of friends. Since it says she has 0 friends, that would mean they have no friends in common and should not be able to see her posts.
The film uses "stock footage," but the words "shutter stock" clearly show in certain images.
After looking at Gustavo Memorial Facebook page, Tyler is comforting Laura on the bed and the boom mic is visible above.
