Although the package for the new region 1 special editon of EVENT HORIZON the 2-disc set is in fact in DTS 5.1. This is a rarity for Paramount, but this film was the 19th film Paramount released theatrically in DTS and it's great to finally have this underrated sci-fi/horror film to DVD in DTS. This is also a great example of superb low-end bass extension that will rattle the concrete from your foundation. Just thought people might want to know just in case they were not buying it because they weren't sure about the DTS.
