The local Fox news channel in Elgin, Texas has posted a news story about Transformers 4 filming in their area. It seems like they will be shooting at the Elgin Cotton Oil Mill. Remember, just a little while ago a casting call was released looking for oil workers. The owner of the mill explained that scenes will be filmed inside the building, but that is all he is allowed to say. Filming will begin there next week.
"I think it's pretty cool you know, it's kind of a different use for these old buildings that have been around forever and it's pretty neat. It's gonna get busy. They said they're gonna have 40 tractor trailer rigs just for equipment when they start shooting next week so it's gonna kind of take over the town sounds like."
