Stanley Kowalski as a character is known to be a very excitable and angry. It is often the case that Stanley gets in fights with his wife and often uses violence despite the fact that at the beginning of the film it is made clear that Stella is pregnant.
It is also the case that Stanley can be considered a petty man because after learning that Blanche was given money to leave Mississippi because of rumors her taking many sexual partners after the death of her husband, Stanley convinces his friend Mitch to dump Blanche.
Finally the character of Stanley can be described as being remorseless. Before the conclusion of the story, Stanley brutally rapes his Blanche in a drunken rage and ultimately drives Blanche into a nervous breakdown, and it is Stanley who has her committed to a mental institution.
Blanche Dubois is a character which demonstrates a great deal of transition. Blanche and her sister Stella come from a wealthy family that has fallen on hard times. It is clear from the beginning that Blanche is character that is in many ways mysterious. She hides her history of love affairs and financial misfortune as best as she can. At the beginning of the story Blanche can be considered stubborn woman, in that she refuses to accept her new lot in life and continues to act like an arrogant, entitled person. She is often rude to Stanley (Although one can argue that this is with good cause) calling him names like “Ape!” and racial slurs like Polack (A reference to his Polish ancestry) and because she is from a rich family she believes that he is not good enough to be married to her sister.
It is the case that the two characters absolutely hate each other and in many ways they are the opposite of each other. Stanley is working class and Blanche is rich. Blanche is beautiful and Stanley is rough. Blanche is compassionate and Stanley is petty. When these two strong forces of nature collide it is no wonder that conflict was created
