I IMDb'd everyone everyone was naming as alternates (who were actually actors and could ideally open a picture)

Viola Davis, Octavia Spencer, etc - they were all currently filming pictures and had like three or four on deck.

And as much emphasis has been placed on the argument that Zoe Saldana could open a film better than the girl from Pariah or *insert OKFamous actor or non-acting singer here*, I betcha her "indie discounted quote" is still lower than Davis' or Spencer's.
