I recently rented the DVD of
The Matrix (which I did see before, when
it was in the cinemas some years ago). Anyway, this disc has some interesting
features. One part I found particularly interesting was the additional
soundtrack consisting only of the musical score and commentary by the composer,
saying how he made various decisions when scoring the film.
(Another nice touch I hadn't noticed before was that, at the start, Neo keeps
his illicit drugs/war3z/minidiscs in a hollowed-out copy of Jean Baudrillard's
Simulation and Simulacra.)
