Actors - and my quick opinion-
Here is my quick thoughts on actors - Our haunt is not HUGE....and we aren't small either - all of our actors are volunteers, 90% of them do it because they have fun and enjoy scaring the hell out of people - the other 10% are friends that may have heard about it and wanted to give it a try....some are good.....some are bad...and some will get better.
My volunteers do it for the love of haunting and it shows - and yes half of them are younger around 16-19 but I have also had a few younger actors, some as young as 10-11 years old....and ya know what they scared the hell out of people. I constantly overheard people talking about how creepy the kids were.
I have been to a number of larger haunts, and smaller haunts - In my experience the larger haunts are awesome to look at and they are fun, they have paid actors....and guess what, the haunt is pushing so many people through back to back that those "paid" great actors have enough time to pop out....yell something...and get back - and most of them the only reason they are there is they are getting paid to do it.
I would much rather have volunteers that are there because they love doing it than have paid actors that are only there for a check.
I love both styles of haunts....I enjoy the small haunted trails put on by schools and other groups because it reminds me of why I love the fall, Halloween, and the magic of it all - I also like the bigger haunts because I enjoy the feeling of walking through a "Haunted" house like you see in movies - is it scary...not to me but I still enjoy it.
To this day one of the best scares I can remember is good old Jim Warfield at Raven's Grin in.....he managed to get me really good with a damn black plastic bag - I was walking by a large glass window and it had black plastic hanging on the other side and I was staring at the plastic trying to see behind it and he slammed it against the window...made me jump back and let out a noise - it was the first thing that had made me jump in a haunt in probably 10 years. So remember sometimes it's the simple things that can really get someone, and I think the reason why is so many haunt visitors have become used to animatronics and other "industry" standards.
