The Boy with Green Hair

Peter's hair turns green the day after he learns he is a war orphan and overhears adults discussing the threat of another looming war. The green hair appears suddenly after a bath, and the film presents it as a fantastical transformation that marks Peter as connected to the war orphans he has been helping in his class project. It serves as both a literal sign of his identity and a magical element that sets him apart.

Peter's class has been working on a project helping war orphans in Europe and Asia, and he has been haunted by the images of children on posters.

The children Peter encounters in the woods are the same war orphans from the posters his class was helping with. They appear to him in a mystical sequence where they materialize among the trees. They tell Peter that as a war orphan himself, he has been chosen to deliver a message: that war is dangerous for children and people must be reminded of this truth.

The posters of suffering war orphans have been haunting Peter throughout the film, and his class project has made their plight personal.

Peter decides to shave his hair after facing relentless cruelty from townspeople and peers, including being chased by schoolboys who try to cut his hair themselves. Despite the poster children telling him his green hair is his message, Peter feels overwhelmed by the hostility and chooses to have the barber shave his head. However, he leaves home that night still determined to spread his message in other ways.

The townspeople and schoolchildren have been pressuring Gramp to have Peter shave his hair so it might grow back normally.

The letter was written by Peter's father for his 16th birthday, to be read when Peter is older. In it, Peter's father shares his core beliefs about things worth dying for and urges Peter to remind others of these truths if they ever forget. This letter reinforces the film's theme that some messages are important enough to dedicate one's life to spreading, connecting Peter's personal mission to his father's values.

Peter is a war orphan because his parents were killed on a European war-relief mission.

The psychologist, Dr. Knudson, tells Peter that when someone truly believes something, they don't run away from it. He explains that what matters is not whether Peter's hair is literally green, but whether his message about war's danger to children gets heard. The psychologist frames the green hair as a symbol rather than a literal reality, emphasizing that conviction and action are what count.

Peter has been running away throughout the film - from his past, from the townspeople's cruelty, and from his own mission.

Peter is devastated to discover he is a war orphan because he had believed his parents simply died on a war-relief mission, not understanding the implication that he was now like the suffering children on the posters he had been helping. The realization connects his own loss directly to the images of orphaned children he has been seeing, making the abstract concept of war's impact on children deeply personal and urgent.

Peter has been haunted by the posters of war orphans throughout the film, and his class project has made him increasingly aware of their plight.

The townspeople react with hostility toward Peter because his green hair makes him visibly different, and they fear what they do not understand. They pressure Gramp to have Peter shave his hair so it might grow back normally, viewing his appearance as something to be corrected rather than a message to be heard. This reaction reflects the film's commentary on how society often rejects those who are different rather than listening to what they have to say.

Peter has already been subjected to teasing about being an orphan before his hair turned green.

The message Peter must spread is that war is dangerous for children. The poster children in the woods tell him that his green hair can make a difference by reminding people of this truth. Peter's mission is to warn others about the impact of war on children and to encourage people to remember what is worth standing up for.

Peter's class has been learning about war orphans in Europe and Asia through their school project.

Peter runs away after the cruelty from townspeople and peers becomes unbearable. The taunts about his green hair, combined with the pressure from the town to shave his head and suppress his difference, drive him to flee. He initially returns to the woods seeking the poster children, but ultimately leaves home in the middle of the night wearing a baseball cap, carrying a baseball bat, determined to deliver his message on his own terms.

The townspeople have been urging Gramp to force Peter to shave his hair, and schoolboys have chased Peter trying to cut his hair.

Gramp Fry is a retired actor who provides Peter with his first stable home after years of moving between neglectful relatives. He offers Peter warmth, understanding, and a sense of belonging that the boy has never known. Gramp supports Peter through his struggles and ultimately encourages him to keep sharing his message, reading him his father's letter and helping him understand the legacy he carries.

Peter has been passed between aunts and uncles who neglected him before finding Gramp.

The film ends with Peter expressing confidence that his hair will grow back green again. This suggests the green hair may return whenever Peter needs to deliver his message, or it may be a symbolic way of showing that his conviction remains strong. The psychologist has already indicated that the literal color matters less than the message itself, so the potential return of green hair represents the enduring power of belief.

The psychologist tells Peter that what he believes shapes what he does, not the hair itself.
