The Hawaiian Marketplace?
That's an interesting observation. I've tried to find out more about the Hawaiian Marketplace and didn't find much out there. Most of the reviews were pretty bad and it sounds like a struggling operation (restaurants opening and closing, stalls selling trinkets made in China, etc.). I suppose they could have been filming someone there, but I'd expect they would go somewhere more scenic than that, like a park, even if they were filming someone connected to the place. If they were filming someone inside the Marketplace, I don't think they would need a permit.
I've seen references lately to the WRP Group doing a show with Ron Howard. Perhaps the filming permit was involved with that production.
