Cost/Benefit of flying I have always looked at like this:
Location: Where are you located? Chicago, Los Angeles, New York, Orlando, Vegas,
etc. and their vicinities, it's not worth doing unless your a college and you want your students to see what it's like to work with them (see if they can guest lecture a group or two as well!), or if you have a large amount of money to burn. Smaller cities, cities without a large
theatre atmosphere (at least one without a heavy amount of
flying effects). will see more benefits from such things.
Audience: Who's your target? Adults will get a kick out of it, as will little kids, the teenager group is probably more like half to a third will probably care enough to enjoy it. What is your capacity to sell ratio? If you are barely getting people in now, you don't have the funds to waste, if you're pulling in enough that you profit already but not as much as you could, keep reading.
Competition: This partly goes back to location, but also one must think of other big shows (concerts, movie openings, other large productions, elections,
etc.) that will be going on at the same time. If there's a lot going on a flying
effect may not draw any more than normal of a crowd to make up or exceed the expense.
Media: Can you
play the media? If you have the exposure and you don't do a flying
effect every year (show), then playing those cards and giving the media the exposure about something really cool happening now, will get you a bigger draw.
Budget: What's your budget? If it all goes towards an
effect and every other aspect of the show blows, well you're not going to get much help from media or word of mouth. The rest of the production should be exemplary BEFORE you start adding (and paying big money) for special things (think renting a G.MA for a
plot of 20
par cans that go up and down twice - senseless right).
Profit: How much do you foresee making (avg. profit per production) without the flying
effect factored in? If it's enough to barely
cover the cost of the
effect and nothing else, I wouldn't do it unless you can get significantly more people in. If you need to make as much money as possible, forego the flying
effect. Most importantly, if you cannot afford to do the
effect according to what your average profit per production is you should not be doing the
effect (loosing $200 on a show is bad, loosing $3-4k is really bad).
Cost: Find out what the
effect is going to cost, how much is: 1 show, 1 weekend, two weekends, three weekends, 4 weekends? If you can do it great, if not, I'm sorry.
Magic formula for the absolutely desperate: If you really can't let the idea go, open the show weekend 1 and get great reviews, let the media (and everyone else) know (keep it as secret as possible until you make an announcement at the end of opening night) that you're doing a huge flying
effect closing weekend that, 'completely changes the artistic direction of the show.' Having already hired the pros and set it up for them to come in (contact them months in
advance so they can get everything spec'd, measured, and checked ahead of time and just have to come in and set it all up) and do the
effect for your closing weekend. If you have enough of a crowd and hype (with a big enough
venue to hold it all), you'll make money. But, the rest of your show has to be excellent to get that amount of media and hype from it, or have a LOT of friends each having a LOT of different friends.
Sorry about the amount of parentheses, I've had an infatuation for them recently, they are very addictive.
