I don't always get what you're saying, may I suggest if you could speak in general terms rather than detailed names and numbers. You mentioned a movie being filmed and walking around the trailers. I have a similar story.
In 1977 when I was living in Pensacola I had heard they were filming Jaws 2 on Navarre Beach, that's on a barrier island between Pensacola and Ft. Walton Beach. I knew a a helicopter pilot and he was the one who told me about the movie set, because he had gone out there to try to get a job flying a helicopter.
That weekend I drove out to Holiday Inn Navarre and parked and walked around. One whole wing of rooms, probably 50 or more had signs in the windows that said everything from wardrobe, to makeup, to costumes. The curtains were pushed back and when you looked into a room you would see racks of clothes or makeup chairs, etc. In the parking lot was a 10' high chain link fence with green canvas so you couldn't see into the lot it was surrounding. At the gate was a private security guard. I just went upstairs to the second level of the motel and got a perfect view of six sharks sitting on trailers, all but one covered with a tarp. I took some photos of the sharks.
Then I went into the lobby of the Holiday Inn, it was actually what they call a Holidome. There were bars, restaurants, swimming pools, etc all inside this sort of mall enclosure with the hotel rooms all facing inward going up several floors. I stood just inside the beachside doors looking down at the pool when a man behind me began walking past my shoulders holding his hands as he was framing a shot. He was telling another man he wanted the camera to move along where he was walking. After a few more photos and no sight of Roy Scheider or anyone else from the movie, we left.
The next year was 1978 and the film opened. It was not nearly as good as the original Jaws, but not as bad as the later 3 and 4 films were. What got my attention was the movie's opening scene and there was a high school band playing next to the pool and the camera came into the holidome filming the scene just the way a year earlier I heard, I guess it was the director, tell his assistant.
On a 1995 trip to Pensacola as I drove along Hwy 98 going west just past Ft. Walton Beach I saw the road to Navarre Beach was closed. I looked out a couple of miles to where the Holiday Inn stood, only to see it was just a skeleton of it's past self, you literally could look right through the building. The entire area was ravished a couple of months earlier by Hurricane Opal and sadly the Holiday Inn Navarre had to be demolisted and has never been rebuilt.
