Sabotage (1953 Alfred Hitchcock) analysis

An example of suspense and shock  is seen in Alfred Hitchcock's Sabotage.In the scene that I watched in class a undercover agent has sent away a Film reel to a young boy to be delivered to a cinema at a specific time.In the film container there is a bomb. the boy is unaware of the bomb he is carrying and encounters a number of situations that hold him up.This brilliantly shows both shock and suspense as the audience is at the edge of their seats wondering if the boy will make it on time and be saved. the shock for this scene is when the boy is waiting on the bus and unfortunately does not manage to make it on time.This shocks the audience as the death of the young boy is quite dark and also the audience becomes attached to the boy and they hope that he survives.
