This is a very good idea, and is something that would be worthy of looking into, to be sure. Perhaps such an undertaking could "piggyback" onto another mystery-related or horror convention, as there would be a built-in audience?
I think too Rush that a Chan venue would do well attached to something else. When Trek conventions first started in Philadelphia they were joint events with Dr. Who.
I've often thought that PBS should run the films again. It's been at least 25 years since my local station ran them.
I'm also thinking of donating some DVD sets to my local library. They don't have a single copy. If more folks saw the films I know they'd love them as much as we all do.
Rush, Janin, thanks for the comments. I did a small bit of research on the very 1st Sherlock Holmes convention 24-26 April 2015 in London (Bendedict Cumberbatch was there :):
1. WWW.SHERLOCKED.COM
DISCUSSION: The website they used to create there event: www.eventbrite.com. It is free if you are not charging anything for registration. And if you are, the fees are minmal. A worldwide event company
2. COST: 1-day $45.00, Weekend (2.5 day)-$68.00
DISCUSSION: I did a calculation using a $10.00 fee for a Chan event, with these results. One thing I learned from past conventions is you have to "Start" with a "target number" of paying participants, unless you have other sources for funding:
Guestimate Number of attendees: 100
Ticket Balance (after fees) $838.00 (Start up $'s to use in hosting the convention)
3. SPONSORS/PARTICIPANTS: http://www.sherlocked.com/index.php/about-us. This convention was sponsored by Massive Events, in association with Hartswood Films and Showmasters.
DISCUSSION: We could-should look for sponsors. Some ideas/interested parties I can think of off-hand are:
a. Left Coast Crime (http://www.leftcoastcrime.org/): These folks host an annual mystery convention (literary) in various locations between HI & TX (CA, NM, OR, etc). Check out their 2017 Convention in Waikiki, HI: Ghost of Honor is Earl Derr Biggers!!! I know they put on a play at their 2009 convention on Muai: The House without a Key.
b. Others might be: Old Town Music Hall, Segunda CA (show films); 20th Century Fox or TCM (front us some movies to sell?); Local Restaurants & Shops (Prizes for a drawing); Individuals (i.e. I can do a first day of issue commemorative cancellation for the event, with U.S. Postal Service)
OK, this is too long. I'll stop know. We need to set a time/venues to discuss further if we wish to go forward, yes?
