Continuity mistake: When Ike and Maggie are on Ike's balcony in NY, at one point they are both sitting down facing each other. Ike gets up to turn the music on and he returns to Maggie. In the wide shot, his chair that he had been sitting in earlier has disappeared. It couldn't be hidden behind the door, because that would make him too far from Maggie when they were sitting face to face.
Trivia: There is no 'Hale' Maryland; the actual town/area used for filming Runaway Bride is called Berlin (also in Maryland). There was such a response from tourists looking for Hale after the movie was released that signs were erected along the highway and on the main street of Berlin welcoming them to Hale.
