I think I have to say Apollo 13. For the short time I have owned this movie, I think that Apollo 13 has some VERY nice deep bass burried inside of those soundtracks. Bad Boys (with Martin Lawrence and Will Smith could be pending. I just bought this DVD this weekend (and the "SuperBit" version at that)) could be pending as well. I got the look at this movie today. I have previewed it on Friday, and from what I can see, since there is plenty of gunshots and explosions in the movie, it might get some merit as a cool sounding movie itself. The Transporter and The Specialist may get honorable mention. Between those four movies, one of them is going to emerge as my reference flick sometime soon. One of them is going to be a reference that is going to be used to test the directional steering as well as deep bass capability for the various surround sound systems that I plan to be auditioning in the upcoming months.
If I am going to be testing video displays however, then Basic Instinct and Spiderman are going to the reference flicks that I will use from my collection. Basic Instinct for color accuracy, and Spiderman for fast action.
