Can you Hire Non-Union Actors in Speaking Roles in an SAG Ultra Low Budget Film

I believe I found... In a round about way... The Answer:
Yes, you can hire anyone in a SAG Ultra Low Budget Film. No, you can't Taft Hartley (but it isn't needed) in a SAG Ultra Low Budget Film.

Or just go to the source: http://www.sagaftra.org/production-center/new-media/faq

Um, that's SAG New Media totally different contract from Ultra Low Budget.

Oh, sorry 'bout that. Here: http://www.sagaftra.org/ultra-low-budget-agreement

Again, I would suggest going straight to the SAG AFTRA site for information. Or send them a note and ask! If it's hard to find this information then their webmaster needs to know as that would be good content for them to create.

SAG AFTRA is a f#cking disaster that I've given up on... And so has most of their members and leadership apparently.
