One major difference between the film and book of To Kill a Mockingbird is _____.
Bob Ewell is introduced very early in the film story
Tom Robinson is more present throughout the film
Dill Harris is a much smaller character
Boo Radley has more lines at the end
The option that excepts the others is Dill Harris is a much smaller character. A movie adaptation was very accurate to the details. It has some differs but it doesn't mention here. But I think the close one to be a right answer is third option.
