At 24:54, while Willowdean is reading Lucy's pageant application form, the application date, Lucy's age and Lucy's date of birth are visible. The date of birth that is shown is 5/5/79, which is incorrect. It should have been 5/5/77, assuming that Lucy was 16 years old in 1993.
When Ellen runs upstairs to get Will for the first day of school (18:27), Ellen's in one outfit -jean skirt and halter top- and then later shown at school in an entirely different outfit -jean overalls and t shirt. She had enough time to change herself, but not wait for Will to change.
When Will finds the flyer for the "Dolly Parton Night Every Saturday Night" in her aunt's scrapbook, the flyer does not have an address on it anywhere stating where The Hideaway is. How did Will and her friends know how to find the place and then claim at the door to not know it was a bar?
