Goodbye Christopher Robin (2017)

Factual error: The musicians in the (real) Band of the Coldstream Guards that plays Happy Birthday for Christopher Robin are wearing their 21st-century uniforms and medals.

Factual error: Christopher Robin and his schoolmates undergo the army medical (which he fails) at the outbreak of war. In fact, Christopher Robin had left school and was at Cambridge by the time the war broke out. In addition, those that pass the medical go off to war in privates' uniforms. As the school (Stowe) is a prestigious public school, almost all would have been commissioned and never served as privates.

Continuity mistake: When Christopher Robin first appears in uniform he is wearing second lieutenant's pips. In the following scene, later the same day, they have disappeared, but he is still wearing an open-necked officer's battledress tunic with shirt and tie. He says he is a private. In fact, he joined the Royal Engineers as a sapper (not a private) and was later commissioned.

Daphne Milne: You know what writing a book against war is like? It's like writing a book against Wednesdays. Wednesdays... are a fact of life, and if you don't like them, you could just stay in bed, but you can't stop them because Wednesdays are coming and if today isn't actually a Wednesday it soon will be.

Christopher Robin Aged 8: Well... you see, after the war there was so much sadness... that hardly anyone could remember what happines was like. Then Winnie the Pooh came along and he was like a tap. You just turned it on and happines came out.
Christopher Robin Aged 8: But I'm not Christopher Robin, really. I'm Billy Moon.

Daphne Milne: I you don't think about a thing, then it ceases to exist. It's true, I read about it. It's all in Plato. It's called philosophy.
Alan Milne: Oh, philosophy. Well, I hope you know you're laughing at Plato.
Daphne Milne: Blue, life is full of frightful things. The great thing is to find something to be happy about and stick to that.
