Goofs

Wen Maddie is standing at the dressing mirror in the Tailor Shop, the belt on her wedding dress moves back and forth in the same scene.

After the car is started by a rolling jump start, the amount of mud sprayed on Maddie's neck changes between scenes.

When James is reading Paul's book, he flips to the Acknowledgements page, which doesn't thank Maddie. The page is full of errors, although the last line is "Edited by Madeline Kelly."

The first three calls Maddie gets from her mother, she picks up the cell phone and brings it to her ear and starts talking without ever hitting the connect button.

This wedding is apparently taking place in both spring and autumn at the same time, since there are flowering Wisteria (spring) in the gardens, and ripe apples (autumn) to pick in the orchard.

When Madeline and her friends get into the taxi from the boom premiere, the reflection of a green screen is visible in the back window of the taxi.

Lough Tay, where the wishing chair is located, is a real location in Ireland but is located in Ballinasloe, Co. Wicklow, which is over three hours away on the other side of the country from where the main story takes place in Westport, Co. Mayo.

The opening credits feature a New York City montage and show people arriving for the book premiere. But the wide shot of the sidewalk clearly shows The Clarence Hotel with its bar called The Curious Mister, both of which are in Dublin, Ireland, not NYC. Maddie says a cab that drove her to the event accidentally took her scarf to Brooklyn, but that's impossible since the premiere did not actually take place in New York City.

When James is reading Paul's book that Madeline edited, a spelling mistake can be spotted: "Throughout" is spelled 'Thrughout." The movie points out that Madeline edited Paul's book various times.

Maddie and her friends met when they were children in school in Des Moines, Iowa. None of the women has a Midwestern accent. This is especially true of Elizabeth Tan, who throughout the film has a British accent. If she had moved to the US as a child and spent 20 to 30 years living in Iowa and New York (she's 34 y/o as of the film), she should have lost any British accent.
