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.
