"These are the real thing. These are the authentic costumes. We wanted to make this exhibit as authentic as possible," said Brad Globe, president Warner Bros consumer products.
Warner Brothers partnered with a company called Exhibit Group to put together the show, which was assembled in several prop shops and then assembled in a warehouse in Roselle, Ill.
"Whether you're six years old or sixty years old you'll find something to love. And I think we all like a little magic in our lives and that's what we're trying to bring with the exhibition," said Eddie Newquist, president, Exhibit Group.
A few things might be a little bit scary for tiny tots, but for the most part it's family friendly.
The Harry Potter series has sold over 400 million books. More than half a billion people have seen the movies.
"Yeah, I think everybody should know and have a little bit of Harry Potter in their lives," said Eddie Newquist.
The exhibit runs through September 27 and costs $26 for adults/ $15 for kids.
