Corrected entry: In the scene that Penny goes to get Mary at Steve's office (after the dumpster scare) she goes in the room, invites him to the movie, and as she tries to make their getaway she grabs a coat off the coat hanger in his office. She didn't come in with a coat.
Corrected entry: The wedding was to be held at a winery in wine country, but when Steve decides to call the wedding off he puts his fiancee in a San Francisco taxi cab and gets into another San Francisco cab to get to city hall. Wine country is not in the city of San Francisco.
Corrected entry: In the last scene, when Steve and Mary meet in the park, it should be June, that's when the wedding was set for, but Mary has a coat on and you can plainly see their breath when they talk.
Corrected entry: When Steve and Mary are looking at the statues, Steve knocks the statue over onto its side. However, its penis breaks off. How could the penis break off if the statue didn't fall on its front?
Corrected entry: When Steve is carrying Mary off the street after she faints, you can see him carry her past the previously 'runaway' Dumpster, which is now standing in the street next to a car.
