The scene and the part in the book were alike because they did sneak up to the house in both stories and after trying to escape from the Radley yard, Jem's pants get caught and he takes them off and runs away. The scene and the book were different because I didn't remember reading about a shadow appearing above Jem making the kids run; I remember Atticus questioning Jem about his pants in the book before he went after them, but that didn't happen in the movie. This scene was different from what I pictured while reading, because I didn't picture them running through a garden to get to the house, which made my 'mental image' different. The background noise and the lighting made the scene... spookier... and the actors did a very good job acting scared at that point.
lol :]
