When my son was little... and we read the books together out loud as a family... he used to dress like Harry with circular glasses, homemade stick wands, a cape, and a scar taped to his forehead.

He would have given anything to be mistaken for Harry Potter!
But seriously... read them now

Don't watch the movies... but read the books. I love to reread them myself every 5 years or so... you won't regret it !!
