Our local town has free friday night movies and will be showing Harry Potter here in a couple weeks. I will be working this event in a 40 foot tent with chairs as well as doing some walkaround and pitching of items. I and am curious how some of you modified some of your presenations to standard effects to fit the Harry Potter audience during the book events mentioned above. I don't have to modify my approach to fit the HP theme. I thought it might be nice to have some effects that play into it though. I know some of you have full blown wizard acts, I don't plan on going this route and can not go to a great expense. I'm really looking for how the presentation of standard effects were modified. Any information would be appreciated.
