Suggested correction: Depending on where the break is, this is possible.

A little later, a 2000s era black SUV is at the curb when Harvey steps out of his camera shop.
Factual error: The Volkswagen Campervan that is used at the beginning of the film has a Zürich number plate, yet the cantonal coat of arms to the right of the number plate is that of the canton of Ticino (red and blue stripe). This is incorrect: The coat of arms should have been a white-blue stripe, which is the coat of arms of Zürich Canton and would correspond correctly to the number plate.
Factual error: When Virginia is attacked by Gosta's cats and throws herself down the flight of stairs to get them off her, her clothes aren't ripped or messed up afterward the way they should have been after such a vicious attack.
Factual error: When Emma and Richard decide to call off the wedding, to provide an excuse to evacuate the church they light a small fire to set off the sprinkler in the side room they are in, but the sprinklers also go off in the main area of the church, forcing all the guests to leave.

Factual error: Late in the big chase scene, Sol climbs on top of the Bentley just as Sinclair decides to drive it straight through a bus that is blocking the highway. Somehow, the Bentley levitates from the highway to about 4 or 5 feet in the air, penetrating the bus passenger cabin rather than impacting the chassis of the bus. Also, as the bus inexplicably explodes in a fireball, Sol (who was atop the car) is torn to pieces, with his decapitated head hurtling straight into the camera. Without lungs or diaphragm, Sol's head is still audibly screaming.
Factual error: There is an ostrich that releases an egg on to his plate, however the bird is a male as females are brown and this one was not.
Factual error: The bar shown in Iqualuit is not real. Iqualuit only has 6100 or so people, and there is no bar like the one shown in the movie. The building is wrong - it doesn't even look like any buildings in Iqualuit. There is one bar that looks nothing like the movie, one Legion, and a bar in the hotel in Iqualuit.

She visits Avilés (Asturias) with Juan Antonio, where he tells her he was born a few blocks from there; however, during their dinner at night the actress mistakes and tells him that he's from Catalonia, instead of Asturian. Anyone with a such an expertise on Catalonia will know that. Besides, it's not real life, but a screenplay, so either Woody Allen screwed up, or the actress did.
Factual error: Spider's club is shown on 125th Street in Harlem, but whenever the officers radio in the location, they say 184th & St. Nicholas, which is in Washington Heights over 3 miles north.

Factual error: Nicolas Cage tasers the dude while shaking his hand with surgical gloves. In reality, I'm sure he would have KO'd himself as well from the shock. (00:06:22)
