Factual error: When Suzanna and Lisa are at Daisy's house, Daisy lays out money for Lisa so that she can get pancakes, and the bill she laid down is one of the new bills. This movie is set in the 60s so of course they wouldn't have the new bills, considering they didn't start making them until 1998.
Continuity mistake: When Susanna is taking a bath, just after Whoopi carried her and dumped her in the tub, you can see that Susanna's hair is combed straight in front of her face. The camera then goes to Whoopi as she talks with Susanna. Then the camera goes back to Susanna and her hair is combed back. Then after another shot of Whoopi, you see Susanna's hair combed forward again. Susanna could not have combed her hair back and forth w/o making any noises from her hands leaving the water. Yet, it was complete silence from the bathtub as the two were talking.
Continuity mistake: Almost at the end, when Winona is talking with the psychiatrist she is lighting a cigarette, and she puts the cigarette box next to her. In one shot we can see that the box is far from her and in other shot the box is near to her.
Continuity mistake: When Lisa is trying to stop the two nurses from going into Susanna's room, she's on a chair with wheels on them. When the nurse (Whoopi Goldberg) decides to go into the room, we see Lisa wheeling towards the door with her. In the next shot, we see that Lisa is on the other side of the hall.
Continuity mistake: In the scene where they are driving the girl to the group home, the car behind them is green and white. After they turn into the driveway, the green and white car is coming towards them, and the car behind them is now a different car.
