Stewart Raffill says he was approached by a man who owned theatres in South America who had an animatronic T Rex which was going to a park in Texas. "The eyes worked. The arms moved. The head moved. He had it for two weeks before it was going to be shipped to Texas and he came to me and said, “We can make a movie with it!” I said, “What’s the story?” and he said, “I don’t have a story, but we have to start filming within the month!” and so I wrote the story in a week." Raffill says all the locations were within 25 minutes of his house. He has stated there was a large fire which took place during the shoot, and that as a result, smoke can be seen in some shots. The first few minutes of the film take place in Newbury Park, California at Newbury Park High School. The film crew kept the local panther mascot and decorations during the filming. Raffill said:
Distribution
Originally filmed as an R-rated comedy horror, its gore scenes were removed from its initial American release in order to appeal to a family audience. In other countries, such as Italy, it was released with these scenes intact. In 2019, Vinegar Syndrome restored and theatrically released the uncut version in select North American theaters. Vinegar Syndrome went on to release the restored version of the film in both DVD/Blu-ray and Blu-ray/4K Blu-ray combo packs.
