Continuity mistake: When Buddy follows his little sister up the tree at the beginning of the film, where they are getting ready for the wedding, they show the mother coming out on the porch and listening in on the conversation. She stands on the porch for a few moments, holding onto one of the pillars and watching her two children in the tree. In the next frame, you see the two up in the tree and under Buddy's arm, you see the mother walk out onto the porch again.
Continuity mistake: At the beginning of the movie Buddy is run over by a train. He is hit by the locomotive at full speed, meaning that it would need hundreds of meters to come to a halt. However, when we see the crowd at the place of the accident the locomotive is right there.
Continuity mistake: In the scene at the nursing home when they're eating the fried green tomatoes in her room, in one shot the old woman is bringing a tomato up to her mouth to eat it and it's half eaten, in the next shot where she actually brings it up to her mouth, there's only one bite taken out of it.
Continuity mistake: In the scene where Evelyn and Ninny eat fried green tomatoes on Ninny's bed Ninny says "the Lord takes us home when he wants us". She stops chewing, musing about what she just said, holding a piece in both hands, but when the camera angle changes her arms are lying on both sides.
Continuity mistake: When Idgie walks back with the stolen honey hundreds of bees are crawling all over her, which show no intention to fly off. The camera cuts to Ruth for a few seconds, and when it cuts back to Idgie when she is reaching the picnic place there's no bee left on her. Besides, there is way too much honey in the jar that can't have come from the small piece of honeycomb she had collected.
