This Collectors Edition is amongst the first discs from Paramount to feature a dts track. It is pleasing to see that the studio is now providing the option for those fans who enjoy the technology, but I am baffled as to why they should do so on such an old movie. The film has had a complete 5.1 remix to take advantage of both the Dolby Digital and dts options, and it works very well. Is there a difference between dts and Dolby on this release? Yes, but it is a very slight difference, with the dts track having a more natural feel, with slightly more clarity in certain passages and tighter bass response, but not a huge difference, and certainly not enough to make the dts option stand out on its own as a selling point. The remix itself is well done with clear dialogue, and some good use of the split surrounds during action scenes. It is an effective, enveloping surround mix, with surprisingly good dynamics.
