A theme is an idea that runs throughout a text. In Blood Brothers, the themes of social class and inequality, superstition and fate, and violence are explored.
Willy Russell asks several questions of the audience through the events of Blood Brothers, particularly about how equal our society is. Through presenting twins, who have the same DNAThe part of the cells of living things that carries information about how they look and function. Everyone鈥檚 DNA is different, except identical twins who share the same DNA. but are brought up in such different families, the playwright shows how much our life experiences affect the opportunities we have in life.
Russell also introduces the idea of superstition through the character of Mrs Johnstone. Should we accept that fate is in control of our lives or are other factors more important?
Another theme introduced in the play is violence. This is present in Mickey鈥檚 life from when we meet him at the age of seven and gets worse and worse until his and Edward鈥檚 deaths at the end of the play.
