Continuity mistake: At the beginning of the movie, when Kenny is leaving with his friends, the truck starts to reverse down the street. His mother looks at him from the porch with her head turned to her right. The truck backs up for about ten seconds at a decent speed as they call back and forth, but his mother keeps looking at the same point to her right instead of moving left with the truck. (00:03:30)
Continuity mistake: When Mrs. Crandell is saying goodbye to the kids, Mrs. Sturak comes outside, sits on the steps and goes to hang her walking stick on the banister. In the next shot she has moved away from the banister and has her cane in a different position. (00:05:05)
Visible crew/equipment: After the babysitter comes, there is a scene where Sue-Ellen is lying on her bed talking on the phone. In her doorway, you can see the tip of a brown shoe, worn by Melissa, just waiting for her cue to walk into the bedroom. (00:09:40)
Revealing mistake: The scene which introduces Sue Ellen working on her new job at Clown Dog firstly depicts people walking in and out of the shop, while the staff serve at the counter. As one family walks out, a boy turns his head to glance directly into the eye of the camera just as he's about to exit the screen frame. (00:17:50)
Audio problem: When the drag queens are stealing the kids' car, Sue Ellen and Kenny look at each other and say "Liza," but both of them mouth "sh*t." This was changed to keep the movie's rating down. (00:28:40)
Continuity mistake: In the scene where Sue Ellen serves cereal in the salad bowl, the milk carton moves on the table. (00:32:25)
Audio problem: In the scene where Sue Ellen goes into Kenny's room and she says "When are you going to start helping me, you lazy little punk?" She mouths "prick" but was later dubbed over. (00:44:00)
Continuity mistake: When Sue Ellen and Bryan are talking on their beach date under the pier, the water doesn't even come close to them until they kiss, when they are suddenly standing in an inch of water for the grunion fish. (00:44:55 - 00:46:15)
Continuity mistake: When Sue Ellen and Bryan are bouncing in the toy store, after he stops and she circles back, he is smiling. Cut to his face and his mouth is closed. (00:53:40)
Other mistake: When Sue Ellen gets the roses from Gus, the tickets in the card have a date of April 6th 1990. This is suppose to be the summer of 1990, which means the tickets are no good. (01:03:00)
Continuity mistake: In the scene where Sue-Ellen has just come home from work, she places her pocketbook on the kitchen island. In the next scene the secretary is going through Sue-Ellen's office and finds her pocketbook and goes through it. How can that be if Sue-Ellen brought it home with her? (01:17:15 - 01:19:35)
Continuity mistake: When Sue Ellen shoots Gus with the water gun, the pattern changes between the closeup and the long shot. (01:23:35)
Other mistake: The movie is set in the summer of 1990 and Sue Ellen has stated she is 17 but when we see her drivers license her birthdate is stated as 12-19-73. That makes her 16 turning 17 in December. (01:24:00)
Continuity mistake: As Rose says goodbye to Sue Ellen at the end of the movie, Sue Ellen's hands are clasped high on her chest. Cut to behind her as Rose drives away and her arms are lowered. (01:34:10)
Audio problem: When the drag queens steal the car, Kenny yells "What are you queens doing in our car?" If you watch closely, his lips are saying "bitches" instead of "queens".
Continuity mistake: In the scene were Caroline and her boyfriend are searching through Sue-Ellen's purse, Caroline is holding both the purse and the license with her left hand, but in the close up of the license, she is holding the license in a different position, and the purse has completely disappeared.
Revealing mistake: After Sue Ellen is hired by Rose, the first time she goes to fax papers the back of the fax machine is visible. Only the power cord is connected, no phone line.
Factual error: In Sue Ellen's resume that she types up, the zip code of GAW is revealed at the top of the page as 90042. GAW is later shown as being in the Downtown LA area. The zip code 90042 is in Highland Park - a suburb several miles away from the Downtown area.
Audio problem: In the scene where Kenny places a plant on his window sill, as he handles the pot containing the plant, you can see it is made of plastic. It then falls and sounds like a clay pot breaking.
Revealing mistake: When Kenny is on the roof shooting the dishes, the sun is behind the house. When the camera shows the actual dishes in the sky breaking, there is a crescent moon in the background. The moon would not be on that side of the sky in relation to where the sun is in the scene, and also the crescent (which always faces where the sun is) is also the wrong direction from where the sun is as well.
Answer: People in LA commute in all sorts of directions for work. And the freeway you see is the 405 in West LA (not the "city" - or Downtown where she worked). This freeway would not even be her direct route anyway. All just made up in the film.
