A Streetcar Named Desire depicts a culture clash between Blanche DuBois (Vivien Leigh), a pretentious, fading relic of the Old South, and Stanley Kowalski (Marlon Brando), a rising member of the industrial, inner-city immigrant class. Blanche is a Southern belle whose pretensions to virtue and culture only thinly mask her nymphomania and alcoholism. Arriving at the house of her sister Stella Kowalski (Kim Hunter), Stella fears Blanche’s arrival will upset the balance of her relationship with her husband Stanley, a primal, rough-hewn, brutish and sensual force of nature. He dominates Stella in every way, and she tolerates his offensive crudeness and lack of gentility largely because of her sexual need for him. Stanley’s friend and Blanche’s would-be suitor Mitch (Karl Malden) is similarly trampled along Blanche and Stanley’s collision course. Their final, inevitable confrontation results in Blanche’s mental annihilation.
