The subwoofer had a whale of a time supporting the music, explosions, and helicopter sequences. It added a nice little floor to the stunt sequences, which account for pretty much the entire second half of the film, without calling attention to itself. Extras Continuing the trend set by Hollow Man , Columbia Tristar have seen fit to bless us with a comprehensive and compelling collection of extras. What sets them apart from the competition is their ability to compress two discs worth of material onto a singular dual-layer disc without making a noticeable compromise in the video or audio quality of the main feature. The menu features an interesting introduction, some animation, a Dolby Digital 2.0 soundtrack, and 16x9 Enhancement.
Navigation is a simple affair, and the menu is quick to respond to user inputs.
The only thing I have to say about this extremely annoying inclusion is that at least I could skip it this time. The commentary is presented in Dolby Digital 2.0 with surround-encoding, as the two participants can be heard in the front and centre channels, while the film's soundtrack is mixed in at a low level with occasional surround channel usage. Much of the commentary revolves around the performances of the actors and the digital insertions, which mostly look quite seamless despite claims to the contrary from critics. One interesting comment is about the lack of visible breath trails at the vertical limit, which critics dismissed as unrealistic, but real mountain climbers apparently told Martin and Lloyd that the air would be too dry at that altitude. It is not 16x9 Enhanced.
