Continuity: The position of Toula's arm around Ian's neck changes between shots when she visits him at the school.

Audio/visual unsynchronized: When Maria is telling her daughter about her life in Greece and why she left, it is obvious that the audio has been re-dubbed.
Errors in geography: A Canada-Post mail truck is visible in the distance, outside the travel agency window. For that matter, the Pappas Grill opposite the street is a well-known Toronto restaurant on Danforth Avenue.
Continuity: When Toula decides to sit at the table full of blondes at college, she places her brown bag lunch on the table then sits down. In the next shot, she picks up her lunch bag and sets it on the table in front of her again before opening it.
Audio/visual unsynchronized: When Toula's mother is talking to her on the phone while peeling potatoes, the sound of her peeling continues when she pauses for a brief moment at the beginning of the phone call.

Continuity: When young Toula and her "friends" are in the car on their way to school, Gus' gloves disappear and reappear numerous times as he is driving.
Continuity: During the proposal, Toula's hand is on her chest during close-ups of her face, but is caressing Ian's face and moves to her side when the camera is on Ian.
Continuity: Later, in the same sequence, she is shown holding an invitation. When Nicki shows her the earrings, she sets the invitation down, but when she says, "I never saw any bridesmaids dresses," she is holding it again.

Continuity: The bridesmaids are shown putting on pantyhose, but then they are shown sliding their feet into shoes barefoot. * A lot of bridesmaids are getting dressed at the same time all doing different things at the same time. Therefore some are putting on pattyhose, and some are are trying their shoes on.
Continuity: While Toula and Ian are on their second date, Toula's purse changes from her left hand to her right between shots.

Continuity: The second time Toula opens the crumpled college brochure in the alley, she accidentally rips a corner off of it. When she places the brochure on her father's desk shortly after, it is intact.
Errors made by characters (possibly deliberate errors by the filmmakers): In the travel agency, Toula is on the phone telling a customer that their reservation is PNR. That is incorrect travel agent lingo - a PNR *is* the reservation itself (it stands for Passenger Name record) - she should have said your seats are confirmed.
Errors made by characters (possibly deliberate errors by the filmmakers): The Portokalos house has Corinthian columns which are said to be like those of the Parthenon. In fact, the Parthenon's columns are Doric, which are much older and simpler than the elaborate Corinthian columns.
