These are the only two I know of that were there besides Howard except the biddies, Don Clark, Virgie, and two male members of her family.
Oh, OK - I forgot about John James - yeah, he was billed as executive producer. Anna and Daniel were just producers. Giancola, the director, owns the studio where they filmed it.
Can’t believe HKS would’ve paid their way down there, though. Perhaps it came “off the top” of the movie’s revenues, lol.
