Final answer:
Irony plays a significant role in the film Shawshank Redemption, such as when Andy Dufresne escapes from Shawshank prison through a sewage pipe.
Step-by-step explanation:
Irony plays a significant role in the film Shawshank Redemption as it helps to create dramatic tension and highlight certain themes or messages. One example of irony in the film is when Andy Dufresne, the protagonist, escapes from Shawshank prison by crawling through a sewage pipe. It is ironic because he uses something that is considered filthy and repulsive to gain his freedom. The irony here is that the very thing that represents imprisonment and degradation becomes the means of escape.
