This documentary, that is on the DVD, spent most of its time talking about the probability of a super-virus that will wipe out humanity. I *thought* the documentary was meant to be about how they shot all the really great scenes in London in the film.
Time spent on how the scenes were shot/created and time spent on make-up effects for the infected was very very minimal. We have been waiting for this DVD since we saw the film in the cinema only to be annoyed and disappointed that a documentary sub-titled "The Making of 28 Days Later" actually spent very little time talking about how it was made. The rest was sensationalist garbage about viruses.
A waste of time watching if you were looking for technical details and secrets of production.
