First, evaluate the films for the sake of the films. In other words, analyze the films. What do you notice about the hand-drawn animation of each film? Is the animation in 1937 (Snow White) different from the animation in 1950 (Cinderella)? How do film elements like the music, lyrics, etc. impact your experience of the films? Remember, this first paragraph should be about BOTH movies.
Then, compare the film to the literature. You can choose either Cinderella or Snow White for this part of the post. Name three differences between the literature versions (be clear which one you're writing about) and the film counterpart. Is plot different? Portrayal of characters? Setting? Other? Break this part of the discussion into three smaller paragraphs–one for each thing you are contrasting/comparing.
End your post with a conclusion–what have you enjoyed most about reading/watching the fairy tales?
