Continuity: Jennifer Lopez's hair changes from one scene to the next throughout the entire movie. One minute she has fresh highlights, the next scene she has two-inch roots, the next she has all dark hair.

Continuity: In the scene where Maximo is taking Steve to meet Mary Fiore in his motorcycle, it starts at clear daylight and end at full night driving a distance that is no more than 30 minutes in San Francisco.

Continuity: Right after Steve rescues Mary from the run away horse, for a split second, you can see the foreign guy's horse in the left hand corner of the screen. In the next shot, you can see that the rest of the riders, including the foreign guy, haven't caught up to Steve and Mary yet.

Other: In the part when Steve rescues Mary from the galloping horse, after he picks her up, the camera takes a "far away" shot, and it's quite noticeable that it isn't Mary wrapped around Steve, it's a dummy!

Continuity: In the scene where Mary and Steve are sitting in the park watching the old movie, Steve starts tossing the colored M&Ms out of his hand and all that's left are the brown ones. A couple shots later you can see that there are colored M&Ms still in his hand, but he did not take more.

Continuity: In the first wedding in the film, the two women who are talking about what a romantic life the wedding planner must lead are sitting. However, the shots before and after their discussions show the entire church standing because the bride is walking down the aisle.

Continuity: In the runaway dumpster scene, the film switches back and forth between a yellow cab going uphill and a red cab going downhill.

Other: At the beginning Jennifer Lopez says that Fran's name is Francine. When they show the wedding invitations it says Frances as her given name.

Continuity: On the day of Steve and Fran's wedding, the part in Penny's hairdo switches sides from shot to shot.
