I managed to find this letter from Troublemaker Studios:
Dear Neighborhood Residents,
Next week we will be filming scenes for the upcoming motion picture Predators, directed by Nimrod Antal and produced by Austin filmmaker Robert Rodriguez.
On November 9th, 10th, 11th, and 12th we will be shooting behind Troublemaker Studios located at 4900 Old Manor Rd. The movie has a heavy emphasis on special effects, so we thought it important to notify all of the residents in the area that you may hear small explosions or gunfire from 7am up until 7pm, on any of the proceeding days mentioned.
We will of course be working closely with the Austin Fire and Police Departments as safety is our paramount concern.
Sincerely,
Logan Cooper
Location Manager
Predators
Predator Planet Films, Inc.
4900 Old Manor Rd.

Already a month old though.
