You need to talk with a business attorney in your state.
> 1 - Having an attractive environment for outside investors.
> Yes we need money!
First off, your investors aren't going to like a DIY company. Second,
you must be extremely careful about raising investment--you must do it
correctly.

The project isn't the entity, the project is the property the entity
owns. You may set up a lean company to develop and produce projects,
then set up holding companies to take title to each individual
project. There's no way you can set up a web like this without careful
planning and contracting, which you will need a lawyer to accomplish.
> 3 - Minimize tax on profit to shareholders.
That's up to their accountants, not your web research. Let them tell
you what they need.
> 4 - Shield shareholders' personal assets.
Yeah.
> After some research, it looks like forming a Serial LLC in Delaware would meet these objectives. However, actual film production will take place in Wisconsin.
By the time you form in Delaware and register in Wisconsin, you will
have spent more than if you just form in Wisconsin in the first place.
It'll cost you less, too, since your average Wisconsin lawyer will
have more experience with Wisonsin companies than Delaware companies.
> 1 - Where should we incorporate and why?
I already told you.
> 2 - Is a Serial LLC best?
Maybe.
> 3 - Should we hire a business-planning consultant?
Hell, no. Hired a damned business lawyer.
Seriously--this isn't like changing a headlight. You have some very
particular needs to be cared for. You can't do it if you're not
trained in it.
