Applying Todorov's Theory to 21

Who are the agents: the protogonist and antagonist?

The protogonist is Ben Campbell, the young white male seen cycling through the city and narrating the 'Winner Winner, Chicken Dinner' story. The antagonist, although unknown for the majority of the film, is Micky Rosa, Ben's MIT Professor. The secondary antagonist is Cole Williams, the security manager of the casino that Micky, Ben and the rest of the team hit when travelling to Las vegas. He can be seen as a red herring throughoust the film as despite him being an antagonist, his actions seem miniscule when compared with Mickys'. 

Describe the Equilbrium 

At the beginning of the opening sequence, a lot of close-ups are used to get a sense of the audience being involved, and instantly draws them into the film. It opens by using a mixture of CGI work, and flashback shots, describing to the audience how they run their operations. The extreme close-up, playing through from 1:22 - 1:26 (actually 2 shots but looks like 1 shot opon first watch) gave me the idea of him getting prepared for something, and the shot at 1:30 confirms this with another ECU of him applying a fake moustache. The black background in these shots make his face look enlightened, and this added together with the framing makes sure the focus is completely on his facial features (binary opposites). 

Is the Disruption of Disequilibrium introduced or hinted at? 

The phrase "That's what got me into all this mess" sets up the films disruption and the disequilibrium is introduced in a very unsubtle way. "And a hand running through perfect flowing meant only one thing... Get out, get out now." is said while, although unknown to the audience at this meant, Cole Williams, the secondary antagonist mentioned earlier is seen chasing towards the camera, which we assume is from the POV of Ben Campbell. As I have mentioned, this is a red herring. The real disequilbrium is Micky Rosa getting 'revenge' and stealing all of Ben's money, taking back his referral towards Harvard Med meaning he is unable to even qualify for an attempted scholarship and has no money to pay to attend there. 

Are there any visual/verbal/aural clues that hint at what the hero's journey might be? 

I feel that the sequence of Cole Williams chasing towards Ben whilst he clumisly grabs all of his playing chips hints that his journey may be counting cards to make money as he says that he has made over $600,000 doing what he does. 

From your knowledge of the film, how will the equilibrium be restored and what will be the new equilibrium? 

The equilbrium is restored by Ben tricking Micky into doing 'one final scam' at which Cole Williams gets Micky back and the chips that Ben has won for his pension. In Cole's last act of kindness, he forces Micky to pay Ben back and re-place his refferal for Ben to get into Harvard. Ben's story of how he counted counts is what makes him 'dazzle' and he gets the scholarship into Harvard Med.
