The novels came out as my son was growing up. He was just a bit younger than Harry Potter and identified with him as his hero. As each book was published, Id read a chapter or three to him before bedtime. Over the years, we enjoyed the whole series.
As the films were produced, wed see each on the opening weekend. Around the third film, my son would dress up in Hogwarts attire! Of course, many of the youngsters at the theater were donning the attire of their favorite characters. It bothered me to see kids dressed as Slitherin!
Theres a Broadway production called, Harry Potter And The Cursed Child. It revolves around the sons of Harry and Draco Malfoy who are friends at Hogwarts years after the events in the novels and films. Its a fantastic story that extends the Harry Potter universe. The play has a spectacular and J.K. Rowling-clever plot, magnificent production effects, powerfully effective music (by Imogen Heap) and special effects that will knock you out.
I was going to see the Broadway production with my wifes family. She had never read the books nor seen the films so we watched them night after night before our tickets date. At that time, the show was almost six hours long so they presented it as a Matinee/Evening combination. You would see Acts I & II then go to dinner and come back to see Acts III & IV. (Since then, theyve re-written the show as a standard presentation.)
If you ever can see a touring production, you wont be disappointed!
