Character mistake: During the opening raid of the FSB safe house, an operator is seen taking hard drives out of a safe. As he does, he states over the radio that they are "SSDs" (Solid State Drives), when in reality they are normal HDDs (Hard Disk Drives), which are noticeably larger than SSDs. (00:07:25)
Character mistake: Dave's wife refers to McCall as his "Army buddy" - but the pictures in McCall's house on the shore show him to be a Marine. Not a generalisation a Marine would make.
Character mistake: When Logan tries to use both his and his mom's phones after her fingers were broken by the Man in Black, he throws them in disgust when he finds the SIM cards have been removed. However, every cell is capable of placing a 911 call regardless of whether a SIM card is present or not.
Character mistake: When Anastasia has to make out the 5 million dollar check to "cash" to get the money to release Mia, she signs the check with her old last name, "Anastasia Steele" instead of "Anastasia Grey", which is written on the top left corner of the check.
Suggested correction: A key point in the movie is how Christian is upset that she didn't take his name in her work life, so it wouldn't be unreasonable that she signed the check using her maiden name (it also could have been just as easily a force of habit thing, it does take time to get used to using the correct name!).
Character mistake: If the nuns in the Abbey weren't real and were created by Valek, why did Valek get one of the nuns to explain to Sister Irene the exact way to defeat her?
Character mistake: At the beginning of the movie you can read the rules of the premises, in particular rule number 3 says; "No guns or any type of weapon permitted through the gates." However, the Wolf King's cronies dump their guns before the gate even when they were never supposed to be able to come in (so does Burke at the beginning, but he was trying to be admitted in).

Character mistake: When Riley is laying in the hospital bed and the detective introduces himself he addresses her as "Mrs. Norris." Her name is Riley North.
Character mistake: Immediately after the crash, when Reeves is carrying his youngest child Sophie, the actress opens up her mouth, even though she has already drowned. (00:14:43)
Character mistake: The tour guide inside the "Degenerate art" exhibition ridicules the 'child-like' paintings of the likes of Mondrian and Kandinsky. In particular he stands in front of Kandinsky "Upward." The German name of the work is "Empor", but the tag says "Empore." (00:03:40)
