Continuity mistake: They mention that the goose has hatched out 7 goslings. They say there were 8 eggs and one didn't hatch. The one egg is given to Templeton, and it is later smashed open. Later that night as they're going to sleep, the mother goose has 7 goslings under her, but then then it shows Jeffrey (one of the goslings) sleeping with Wilbur. Seems they had an extra gosling with the mother.
Wilbur: Are you writers?
Charlotte's daughters: No, but we will be when we grow up.
Wilbur: Then write this in your webs, when you learn: This hallowed doorway was once the home of Charlotte. She was brilliant, beautiful, and loyal to the end. Her memory will be treasured forever.
Charlotte's daughters: Ooh, that would take us a lifetime.
Wilbur: A lifetime. That's what we have.
Charlotte: Chin up, chin up / Everybody loves a happy face / Wear it, share it / It'll brighten up the darkest place / Twinkle, sparkle / Let a little sunshine in / You'll be on the right side, looking at the bright side / Up with your chinny-chin-chin.
