Toy Story 3 Opening Sequence Analysis

We watched the opening sequence to Toy Story 3 and analyzed the various conventions of it. in the first 29 seconds of the introduction, there is the Walt Disney film theme tune used to establish a light and cheerful mood, which is a typical convention used in Walt Disney children's films.
After 43 seconds into the opening sequence, the titles are introduced and the theme tune used here creates a climatic and exciting mood, which is a code that is commonly used in an action children's film.
The first location of the film is a desert, and this location has been established using a tracking shot, and the background music that is used here continues to maintain the climatic element of the opening sequence, but it establishes a darker mood, as opposed to the lighter and more cheerful mood established earlier on in the sequence.
The main characters in the opening sequence have been established in the following ways:-
MR POTATO HEAD: Establishing shot used to show him off as a villain, low angle shot used to show him as the less powerful character (the villain).
WOODY: High angle shot used to show him as the dominant character (the hero) which is code of an action children's film.
Mr Potato head is also wearing an eyepatch and is seen holding bags of money, which make it clear that he is the villain in this opening sequence as it is a stereotype in children's action films for the robber to be carrying bags of money.
Woody however, wears a brown hat, a cowboy shirt and blue jeans, which are clothes that a typical children's film western hero would wear.
When Woody and Mr Potato Head confront each other on the top of a train, which is seen as a convention of this particular film because it sets the scene and makes the events that take place more climatic and challenging for the hero, which builds excitement and tension and therefore is entertaining to children.
