By applying symbolic codes the director has shown the relationship between Billy and his father Jackie Elliot to be quite unique. Throughout the film the relationship between Billy and Jackie change. In the beginning Jackie is very easily worked up, about the miners strike and the loss of his wife. This anger he takes out on his sons forcing them have to act very tough. In his time Jackie was a great boxer, therefore he wanted Billy to do boxing in order to become strong and fit. What Jackie didn't know was that Billy was suffering greatly during these lessons, he just was not fit for boxing.
Throughout the film the director has used symbolic codes and technical codes. If the audience did not understand the relationship between them, the plot would be hard to interpret. This is giving every viewer their freedom to their own point of view. This strained their relationship a lot, as Billy just wanted to keep out of Jackie's hair and keep doing his ballet. At the end of a film one is usually able to see interviews with the actors, explaining their characters and telling the audience what they liked best. This was hard for Billy to understand as he was at the age where he always asked questions, and short-tempered Tony was not happy about it. If it were not for Mrs Wilkinson, the plot would not be the same, and it would make it harder for the audience to see the love and friendship
