in the opening two mintues of the shawshank redemtion there is diegetic sound at the beggining where the three jail mates at the are talking and the other jail mates around the are talking about being up for rejection then the character played by morgan freeman is a scammer in the jail and starts to narrate about how he is the guy to get things for you if you needs it by this he is shown to the audience to be a main character , at this point in the opening the audience feel that the jail mates talking now are experienced and know what to do and what not to do in jail and knows the ins and outs about the jail. and then explains about andy (the main character) why he is in jail and a breif background for the auidence. also the birds cheeping in the background. There is also non-diegetic sound played over the top as the new caoch of jail mates comes in.There is a long shot of the bus as it goes into the jail. a high angle shot of the bus also. in the opening there isnt much going on just a breif introduction on the background of everything and where the movie is going to be set.The audience see how vulnerable the new jail mates just coming in on the bus are this shows the fear factor of how people would feel going into a jail and tries to reflect on you wondering whether you would feel the same or brake down first and how you would tackle the situation that you have gotten into.Andy shows no emotion to show his vulnerability and keeps a straight face showing no fear which to the audience shows a heroic feel to him.
