Corrected entry: When Father Moody comes to talk to the family, he finds Mr. Lisbon having a beer as he watched a baseball game on TV. His beer was a Corona, which wasn't brought to the United States from Mexico until the 1980s.
Corrected entry: In the scene where Trip and the guys are sitting in the car waiting to go into the Lisbon house to pick up the girls for the homecoming dance it is dark outside. When they are all in the car on the way to the dance it is definitely daylight.
Corrected entry: In the scene where the Lisbon girls throw their first and only party, all the girls introduce themselves to the neighborhood boys they invited. One of the girls shakes hands with Tim and says, "Hello, I'm Bonaventure" and so on. Later in the film, Mary is at her locker when one of the boys says, "Hi, I'm David." Mary replies, "I know who you are. I've only been going to this school my whole life." If all knew each other in advance, why did they have such grand introductions at the party?
