Applying Todorov's Theory

1.)  

Protagonist - Tarzan

Antagonist - The Leopard 

2.)

The equilibrium in the opening scene is shown by two separate happy families living their lives. One family is made up of three humans, (the parents and their son Tarzan,) who have crash landed on an island, and had to rebuild their home. The other family is three gorillas (the parents and their son.) The human family (although crash landed on an island,) happily work together to rebuild their home. We get a sense of equilibrium with the upbeat and motivational music, and the family seem to be enjoying themselves with their happy expressions. The gorilla family live in the jungle amongst other gorillas. The baby gorilla plays with his parents and all seems well. We see how similar the families are as the humans would do something, and then we would see the gorillas doing the same thing. For example, when the father is looking proudly at Tarzan, and the camera cuts to the gorilla father looking proudly at his son. This suggests that the families are linked in some way, and that they will meet at some point in the future. 

3.)

The disruption to equilibrium is obvious when the word "danger" is sung as part of the background music, and it fades from a sunny scene showing the humans finished house, to a close up of a leopard at night time. The leopard then eats the baby gorilla and kills Tarzan's parents. :(

4.)

There aren't really any clues as to the journey of Tarzan at this point, as later on in the film, we find that the leopard isn't actually the main antagonist, and we are introduced to Clayton, (an evil man with a rifle.) However, it is likely that the story will be about the relationships between Tarzan and the gorillas, as family is a main theme in the opening sequence.

5.)

Equilibrium is partially restored when Tarzan gets revenge on the leopard by killing it. However the main disruption to equilibrium happens around the middle of the film, when Clayton comes up with a plan to steal some gorillas and sell them. Equilibrium is restored when Tarzan saves the day by putting a stop to Clayton's plans (by killing him,) and saving the gorillas. The gorilla father (Kerchak) dies in the process. :(
