One of the many things that struck me as amazing when I met my brother-in-law for the first time was his ability to disappear into his room and re-emerge a short while later dressed as one of the characters he'd just watched on A-Team. His toy box was full of "props" that helped him transform into any character he chose. I don't know if he ever watched movies with his mother, but it wasn't much of a stretch to imagine he did, and to put that to use in my story.
