When they toast Hadley, the fruit wedge on the glass of Terry's bloody Mary changes from a lime to a lemon between shots

When Denny and Terry are sharing ice cream from the same container, Denny puts his spoon in the container twice without removing it between shots.

When Hadley is going back to college and loading the SUV, the neighbor passes by walking the dog, right to left. When she is getting into the car the rear end of the dog is seen again walking by, right to left, thereby making the dog and owner walk past the car twice in a few seconds.

Just before Hadley's wedding, when they are talking in the bedroom, she says she's showing and then you see her stomach. She's not obviously pregnant, although it does stick out a little. Then, after the wedding, they show her dancing with her new husband and her stomach is then poking way out, as if she grew 5 months' worth during the wedding.

Rearview Mirror is missing in a scene in her car.

The State of Michigan eliminated the requirement for all cars to have front license plates in 1974, which still stands to this day. All of the modern cars in this movie have front and rear license plates.

In the credits, thanks are given to Universal Pictures for allowing them to use a still photo of Kevin Costner from "For the Love of the Game". The first "the" is wrong, the correct title is For Love of the Game (1999).

In the closing credits for use of a clip from "The Tonight Show," The show title is spelled as "Tonite."

Both Terry and Denny mispronounce the name of Halley's Comet, saying Haley's Comet instead.

The Detroit People Mover (an above ground monorail system) runs on a west-east circular course (counter-clockwise / right to left) when viewing it with the front of the Renaissance Center in the background. A shot of the Renaissance Center from its front showed the People Mover moving left to right (east to west according to that shot), against its normal route. However, during construction downtown the People Mover sometimes is not run full circuit. Durring renovations it did not run a full circuit until the later half of 2004, but could have been during shooting.

When Denny breaks down Terry's bathroom door it makes for a very dramatic scene. However, Denny would have no idea where she would be standing on the other side and she could have been seriously injured.

When Denny and Emily are dancing at the wedding and then the camera cuts to Terry, equipment is reflected in the glass door behind her.

When the family limo at the beginning and end of the movie is returning from the funeral, the opposing car is seen driving away from the camera on the right side of the road instead of on the left side, which would have never happened in Michigan.

Every attempt is made to show the Wolfmeyer home in Bloomfield Hills, Michigan, however the drivers license shown is from West Bloomfield and has the zip code listed as 66020 which is for Easton, KS and Bloomfield Hills, MI is 48301. The address listed is 1246 Puritan Avenue. There is no Puritan Ave in either Bloomfield Hills or West Bloomfield, MI. Also, in Michigan the license expires on a person's date of birth and the license # starts with the first letter of the persons last name. In this case both of these are in error.

At the graduation commencement, Stephanie Winnington's name is announced out of alphabetical order.
