Go to the part in the movie where Jem, Dill, and Scout are sneaking into the Radley's back yard. There is one part where they are all sitting in a collard patch looking up at the house. The camera gets three individual shots of each of them staring at the house. Then Jem says, "Come on!" and they all move forward. As they are moving foreward, look behind them; one of the collards in the collard patch moves! And it doesn't just move like somebody brushed against it, it visibly starts to wilt down to the ground. Just what kind of plants are those Radleys growing in that backyard?
