Continuity mistake: When Nick is telling the doctor about his new cottage near the start, he goes to his porch with a book and stands next to one of the pillars. In a wide angle, he is standing next to a pillar with leaves around the pillar, but in a sudden close-up the leaves around the pillar have vanished. (00:04:40)

Revealing mistake: When Nick starts talking about Gatsby to his doctor, a green reflection is visible in the doctor's glasses when the doctor says "Where'd you meet him?" There's no other object in the room that is that style of green (it's most likely a green screen). (00:03:00)

Continuity mistake: In the beginning scene, Nick has a conversation with his doctor in the Perkins Sanitarium. The shot after Nick says "When I came back from New York I was disgusted" shows the doctor open his file. When he opens up the file, Nick's name is placed next to patient name and below it is "Patient Report (by board of examiners)." In this shot the "N" is directly above the "Y" in "by." But in a quick close-up of the file,"N" is now directly above the "O" in "board." (00:02:00)
