Factual error: At the beginning of the movie, we find out that Holly and Gerri were married when she was 19. She then turns 30, so at least 11 years have passed since the day that they met. However, when Holly sees Gerri in the pub on the day that they meet, he sings "The Galway Girl". This song was not written by Steve Earl until 2000, and they must have met sometime around the year 1996.
Continuity mistake: When Holly and Sharon are showing the apartment to the couple, in the first exterior shot from the street, as we hear Holly's voiceover and see her in the center window, all of the window shades on the left are halfway down. In the next interior shot, the shades on the right and left side are up near the top. (00:40:15)Super Grover
