Goofs

Lux's pants change from when she gets up from the couch in the living room to the shot of her showing Trip the door.

The amount of peach schnapps in the bottle changes from almost half empty to full when Trip hands the bottle to Lux's sister.

The girls are shown playing an Atlantic Records promotional single over the phone, but the song heard on the soundtrack is of an artist who never recorded for Atlantic.

When Peter comes over to the Lisbon house for dinner Cecilia's bandages disappear and reappear between shots.

When Trip is pinning the flowers on Lux's dress, the camera pans down to her hips and a round 'inset' window appears, revealing that Lux is wearing pink panties under her dress, with Trip's name scrawled on them. The brief shot also shows part of her bare thighs and tummy. Yet when Lux is making out on the grass with Trip, we can see she's wearing white pantyhose (or tights) under her dress.

During the end credits, one of the Sloan songs is titled as "End it Peacefully" when its actual title is "The Lines You Amend" from the album "One Chord to Another" released in 1996.

The decimal value of pi shown over the blackboard in Mr. Lisbon's class is incorrect starting at the eleventh decimal place. It's shown as 3.141592653594298... but the correct value is 3.141592653589793... This is shown at about minute 32 and minute 46 in the movie.

Above the blackboard in Mr Lisbon's classroom, when he explaining "unions" and "intersections" (at approximately 34 minutes), the value of "pi" is only correct for the first 10 decimal places.

One of the televisions showing a news report on Channel 8 is clearly tuned to Channel 3. There is no cable box visible, revealing that the TV screen image was from a videotape fed through a coaxial connection (requiring the set to be tuned to the default coax input channel, 3).

When the girls are locked up in their house, the front lawn is slowly covered with brown leaves to show the passing of several weeks. However, there is only one tree on the front lawn, and its leaves are green. The surrounding trees are also green and none of them show evidence of falling leaves.

The day and date of the first entry of Cecilia's journal that is read aloud by one of the boys in 1975 would have to have been in 1967 to be correct. However, it is written in very legible cursive letters--unlikely for a five year old girl (Cecilia was 13 in 1975).

A song playing on the radio when the girls are driving to the homecoming dance is Sloan's "Everything You've Done Wrong", which was not released until 1996.

As the Cadillac carrying the sisters and their dates is driven home from the dance, a white Honda Civic hatchback (circa 1988 - 1991) appears parked on a driveway in the background. But this scene takes place during 1975.

Judging by the tree removal notice and the ambulance license plate, the main action of this film occurs from June to October of 1975. However, several songs and LPs featured in the film were not released until 1976.

When the Lisbon sisters and the boys are playing music to each other over the phone, the song chosen by the girls starts playing while the head shell/needle on their turntable is descending, before it makes contact with the record.

When the girls' father takes a picture of them, we hear the whine of a flash charging, but dad's Instamatic doesn't have an electronic flash - it uses a flashcube.

During football practice, right after Kevin Head offers Trip three joints to take one of the Lisbon girls to homecoming, the shadow of the boom pole is visible on Trip's head and back.

The father refers to his model airplane as a B model North American P-51 Mustang in British service, however, the model aircraft is actually a Curtiss P-40 Warhawk.

In the scenes in Mr. Lisbon's classroom there is a banner above the chalkboard that displays an incorrect value of pi.

When Trip is introducing himself to the movie, he talks about the first time he met Lux. He says he met her for the first time when he walked into the wrong history class. But when they show him walking into class, the door says Language Arts.

The city Grosse Pointe is misspelled "Gross Point" on the tree removal notice.

The character "Jake Hill Conley" was originally called "Joe Hill Conley" in the book on which this film was based. During a scene of the girls' home incarceration, where Therese is reading on one of the beds, Mary is applying make-up to Bonnie, and Lux is sitting on the window seat, he is incorrectly referred to as "Joe Hill Conley" by the narrator.
