Sarcasm In "Miss Representation"

During this past week we have watched a movie called miss representation. This film was about women and how they have been used as these kind of marketing objects in the advertising world. We were looking for devices like tone and irony. Me and my partner got sarcasm as our device. I only only found one representation of sarcasm. Sarcasm is when something is said but not meant to be taken literally. The one sentence in this hole movie was when the narrator said "and they replaced her with Drew Carry, because he's so fit". They used sarcasm to prove a point in this movie that women still aren't treated with respect like men are.
