Taxi Driver

This is the final scene of the movie "Taxi Diver" by Martin Scorsese, in which the protagonist Travis Bickle (Robert De Niro), an ex-Marine who drives a cab, goes and saves little Iris (Jodie Foster), a 12 year-old prostitute who is controlled by a pimp called Spot. Travis is a depressed guy disgusted by the city in which he lives in, specially of violence and prostitution, and that's why when he meets Iris and discovers she is trying to escape from Spot, he decides to help her. 

We can find out several changes in the life situation of the main character during the scene; the main value change I would like to talk about is cowardice/courage. Throughout the movie, Travis looks the city ripping apart, but he never says or do anything, until now. He could be considered as a coward because of his apathy and disinterest for live but by the end of the movie (and of this scene) he rescues Iris and releases her so that she could go back to her parents house. The fact that at the end of the movie there is a newspaper in which they write that Travis is a hero, not an assassin, makes it even more credible. I thought another value change could be that at the end he dies, but while analyzing the scene, I discovered that we don't know if he dies; Travis is really ill, but he doesn't die. 

To find the beats in the scene we must find every exchange of behavior; from the moment in which Travis gets down of the cab, until he saves Iris.  He walks across the street and find Spot in a porsche, talks to him in a very friendly way (Beat #1), then they begin fighting and Travis talks in a sarcastic way (Beat #2). Spot gets really angry and kicks him, so Travis takes out his gun and shoots him in the stomach (Beat #3). He walks down the street like hesitating of what he is doing or waiting for something and then decides and goes in the building were Iris works (Beat #4). Travis goes in the building and shoots an old man in the hand but Spot shoot him in the neck (Beat #5), so he turns back and kills him. Our protagonist goes up the stairs, were he is shot again by the guy who was with Iris (Beat #6), Travis falls down but takes out another gun and shoots the guy. Finally, the taxi driver kills them all, incredibly he survived the shoot-out, but he tries to kill himself (Beat #7), but he is out of bullets. At the end, the police arrives and Travis moves his hand like if he was shooting himself (Beat #8).
