Resumen: The Godfather (Francis Ford Coppola, 1972) shaped the figure of the Mafioso in the mafia genre during the 1970s through the emblematic character of Vito Corleone (Marlon Brando), distinguished by his Italian mannerisms and strict moral codes. This dissertation analyses Brando’s performance as Corleone in relation to the phallic masculinity present in the Mafia ethos. Particularly, I discuss the principles that guide the Mafia in men's interactions during the opening scene of the film. Secondly, this dissertation also explores the role of the female figures in the male-exclusive world of the Mafia. In particular, I analyse Kay’s (Diane Keaton) decisive role in challenging women's helpless position in mob life, in which they are perceived as a threat to Men's unity. Her distinctive character and her relationship with Michael guide the audience through the codes of masculinity that relegate women to the private sphere.
