One of Billy Elliot’s strongest themes is that society, and individuals, should not be limited by stereotypes. This includes stereotypes and assumptions of gender roles as explored by the main plot of the film. Billy’s assumptions of gender are the first to be challenged in the film and the audience can quickly see a chance in the protagonist’s attitude. Jackie also experiences a change in attitude towards gender, although his change does not come as easily.
In this scene, Billy’s position on gender roles is revealed, and the audience cannot help but feel that Billy’s opinions reflect society's expectations about how males and females should act rather than his own personal thoughts.
This scene not only demonstrates Billy’s change in attitude towards gender roles, but also highlights Jackie’s seemingly embedded attitudes.
This scene is paramount for the development of Jackie’s character. Here, we see Jackie not only accepting his son’s decision to dance, but also making personal sacrifices to support Billy.
Gender is at the center of Billy's problems, even though he sees no issue with his interest in ballet. In the town where he is from, boxing is for boys and ballet for girls, yet Billy's deep love for dance draws him towards ballet nonetheless. At first, he himself is confused about whether his interest in ballet belies some kind of effeminacy, but soon learns that male ballet dancers are some of the most athletic men in the world, which reassures him.
Even though it doesn't take Billy long to learn that ballet doesn't make him less of a man, it takes his brother and father awhile longer to catch up to him. They are convinced that ballet is for women and gay men, and their bigoted attitudes prevent them from seeing Billy's immense talent. Their perceptions of gender prevent them from accepting what is right before their eyes.
Additionally, Billy's best friend Michael is coming to terms with being gay, experimenting with cross-dressing and his own effeminacy. While Billy's discipline of choice, ballet, marks him as subverting gender expectations, Michael grapples with the fact that he isn't like other boys in key ways. Billy, an ever-sympathetic protagonist, accepts Michael and encourages his friend's effeminacy, bringing him up to the gymnasium after hours and putting him in a tutu.
