Other mistake: Anna is shown from the front as she ascends an ice staircase inside Elsa's ice castle. There are giant ice pillars to Anna's right and left. They should reflect the side of her face, but instead the reflections show her face from the front.
Suggested correction: That's not how reflections work. The ice walls are about two feet to her side so the reflection would look like it was shot from the front but about 4 feet to the side.
Other mistake: When Wallace is listening to the old voice mail message from Megan, it shows Megan's phone number as 416-555-0977. When Wallace looks at the phone number that Chantry gives him, it's the same number - 416-555-0977. (00:01:00 - 00:06:25)
Other mistake: When the husband breaks into the old lady's house and checks her voicemail, it says that Katie left a voicemail Monday at 11:47am. When the husband calls the restaurant, the recording says they are open from Tuesday to Sunday. So Katie shouldn't have been at work.
Other mistake: At the very end Nick writes "The Great" in ink above the typed title "Gatsby" on the cover of his manuscript. The E in "The" is a completely different style to the E in "Great."
Suggested correction: It is the therapist who writes The Great. As for why the Es look different, not everyone one is able to write their letters the same every single time.
Other mistake: When Estefania and Amadeu first meet, she attempts to light a cigarette while talking, which is impossible - you have to have both lips together to hold the cigarette still for the match to light it successfully.
