David Heyman Interview

"J.K. Rowling came to the set and saw our wands. She thought they were too
ornate, so we simplified them."

There is an interesting interview with David Heyman, Producer on all four Harry Potter films, here on Metro in their 60 second interview slot.

"Harry Potter fans are a hardcore bunch - have you done anything to upset them? - In the fourth film there was a picture that was sent out too early that depicted an incorrect name written on a gravestone. That was something we had corrected but there was still a huge amount of fan outrage when they saw it."

So fans can effect the making of the films?

Heyman confirms that actors Alan Rickman (Snape) and Ralph Fiennes (Voldermort) have been able to ask J. K. Rowling about their characters!
