I did not see mention anywhere about the locations in which this movie were filmed.
It just so happens that I am one of the people who worked on this film, so for anyone who happens to be curious enough, I can tell you all about it. During the filming, I was working as an Armed Security Officer for a small company named Central Park Patrol. There was another man named Hilario Gomez who worked with me and together, we provided 98% of all of the security for the crew and equipment. The locations were probably chosen by a man named Craig Busch (I would have to verify it in the credits on the print), who had worked as the location manager for a number of films shot in the Houston Metro area (Robocop, I Come In Peace, Etc.) Our Primary locations were in the Houston Heights and Galveston, because that is where most of the Victorian Architecture can be found in houses of this area. One of the locations that was not in these areas was 'The Isabella Courts' apartment complex located at the corner of Main Steet and Isabella Street.
If my memory is correct, we used an old building that was originally built as a print shop for bank documents, stocks, bonds, and checks for our sound stage. We also used this same building again for the HBO movie 'The James Brady Story' and the Motion Picture 'Rush'. In the late 1990s, this building was converted into 'lofts' and sold off to the tenants.
At any rate, I will always remember the first day I worked on this film, standing in full uniform and guarding the equipment trucks. Treat Williams came by (finished with his day's work) and spoke to me. He was carrying a can of Budweiser beer. He offered it to me and I politely refused it. I explained that I was still on duty. He laughed and said 'have it when you get home.' I put it in my car, and since I didn't drink beer...just the harder stuff...I put it in the fridge when I got home. I believe that my wife drank it a day or two later. It was great to meet Treat and find out what a really friendly guy he is. I have been a fan ever since. I especially loved the TV series Everwood while it was on the air.
