Corrected entry: When Lucy gives Edmund the healing elixir, which "heals any injury", his life-threatening abdomen wound is healed, but the gash on his lip remains.
Corrected entry: Towards the end of the film when the children become adults, the eldest sister's eyes are a very dark brown color. When they fall back through the wardrobe cabinet they go back to their original steel blue color.
Corrected entry: When Lucy came out of Narnia the first time, she was only gone for a few seconds. 5 to 10 seconds at the most. But when she goes in the 2nd time, Edmund goes in at least 30 seconds after Lucy. Wouldn't Lucy have already returned if time basically stops in Narnia?
Correction: I suggest you read "The Voyage Of The Dawn Treader", one of C S Lewis' later books about Narnia (filmed by Disney in 2010). In the first chapter of "The Voyage Of The Dawn Treader", you will read, and I quote directly: "Narnian time flows differently from ours. If you spent a hundred years in Narnia, you would come back to our world at the very same hour of the very same day on which you left. And then, if you went to Narnia after spending a week here, you might find that a thousand Narnian years had passed, or only a day, or no time at all. You never know till you get there."
Correction: Time doesn't stop in Narnia, it goes a lot faster. Lucy and Edmund eventually met up in Narnia the second time so it makes sense that they came back together. Lucy just spent a much longer time in Narnia than Edmund the second time she was there.
Correction: The reason that it wouldn't heal Edmunds lip is because the potion is made to heal the most threatening injury or illness. If the injury is something minor, it most likely will not be healed. In the book "The Voyage of the Dawn Treader", this is explained when Eustace's arm ring won't come off even after being healed by Lucy's potion. It will stop the pain, but it will not heal the injury completely.
