To Kill A Mockingbird Movie vs Book

There are several differences between the movie and the book. One major difference was the scene when Dill and Jem tried to communicate to Boo Radley. In the book they tried to leave a note in his window. In the movie they tried to look in the window. Then when they ran away and Jems pants got stuck, they left out the part when Atticus made Jem explain were they were. 

A second major difference is Tom Robinson's arm. In the book his arm was crippled in the movie they didn't mention anything about it. In the book when Tom was shot while trying to escape they said he would have made it if he had a normal arm. In the movie they left that sentence out. The movie and book were different in several parts.
