ANYWAY....
To bring it back to the topic at hand, I think that such a crowdfunded campaign of a TF/TG movie with practical effects could work only if the potential filmmakers already have a "portfolio" of past works to show.
If you're asking people to throw money at a project wherein there is no résumé to look at,
you're going to have a bad time.
In other words, if you can't show that you can already do it, you won't get the money to do it. Rick Baker didn't start out making "An American Werewolf in London". He started out making effects like
this.
You need work under your belt before you can ask the public for funding. Are there any filmmakers with an established body of work that have expressed a desire to make a TF/TG movie (or even short) with practical effects?
