- In the trailers, whenever Ian has to use magic, he seems a bit unsure of himself. It doesn't help when Barley is behind him all the time telling him what to do and how to focus. One instance occurs when Ian can't focus on making the canister of gas grow, and instead shrinks it. So when he can't take Barley telling him to focus anymore, he quickly gives up.
- The fact that the plot of the movie kicks off because Barley and Ian want to bring their father back to life for Ian's sixteenth birthday. Even worse is the reveal that Ian doesn't remember their dad, either because he wasn't born yet or he was too young to remember him.
- The third trailer begins with Ian listening to a recording his dad had made. It's his forlorn expression when it ends that sells it.Mr. Lightfoot: Long ago, the world was full of wonder. It was adventurous. There was magic. But it wasn't easy to master, so the world found a simpler way to get by. But I hope there's a little magic left... in you.
