Character mistake: On two occasions throughout the film, Kraven's accent changes - once when he is talking to Lucian near the beginning of the movie and near the end of the movie when he is telling Selene that Viktor killed her family.
Character mistake: Although Dr. Kalarjian said that there is a "code blue", which means a patient requiring resuscitation or other immediate medical attention, she wanders over there without rushing at all.
Suggested correction: When she was getting closer, she started rushing more. It took a while for her to get there but maybe that was just done to fool the audience. Kimberly did think she was going to kill Isabella after all.
Character mistake: When Duddit's mom is packing his lunchbox, she refers to him as "Henry". (01:45:54)
