Some thoughts from the production corner,
Superheroes screenplays are great to produce in many ways: the usually consist of a conglomeration of components that define successful commercial movies:
-adventure
-action
-drama
-love story
-strong, well defined lead characters
-strong well defined enemy
-G or PG13 rating
-amazing marketable power for ancillary markets
From a pure marketing/financial perspective, they are great.
HOWEVER, there are reasons you don’t see too many indi superheroes films:
From the production perspective, they are a nightmare:
- to make it commercially viable the budget is well above indi standards (and by indi standard I mean 1-5 million)
- to make it commercial viable you need an established superhero andlicensing such rights is financially impossible for most indi production companies
- and finally, the alternative - the processes of introducing NEW superheroes - is even more expensive than making the film
NOW remember I am talking from the indi producer's corner. This may not necessarily affect your writing. That is, nothing prevents you from writing a good sp about an established hero and try to get sell it to a studio, or a indi producer with studio affiliation, or an indi producer with tons of money (which 99% have studios deals).
So what I mean is that you most likely will never get your superhero script produced by an indi filmmaker, unless you envision a new-media vanguard guerilla style short.
Cheers,
