Other: In the end credits, Christopher Walken's name is listed as 'Christopher Wlaken'.

Factual error: When Alvy and Annie try to get the escaped lobsters into the pot, the lobsters are red and orange. Live lobsters are dark green and black - they turn red/orange after being boiled.

Continuity: In the scene where Annie is driving Alvy uptown after tennis in her VW, she spots a parking space on the street and quickly pulls in behind a parked, driverless, red station wagon. Immediately, in the next shot, as they are opening the car doors to get out, they are behind a blue car.

Visible crew/equipment: At the very beginning of the scene where Alvy and Annie are arguing over Annie's adult education teacher, David, and Annie is getting into the cab, a film crew member is visible up the sidewalk, just above the roof of the cab. As the scene starts, he drops his arm as a timing signal to the old woman carrying a grocery bag to begin her walk into the scene, where, seconds later, Alvy turns to ask her a question.
