Making of Resident Evil is a documentary short, which was released as a featurette in DVD copies of Resident Evil.
The Undead were designed to be recognisable, but distinct from zombies of the 1970s and '80s films. The actors included professional dancers who could be taught the same choreography. The make-up was based on real diseases found in medical dictionaries. Fowler gave skin tones to the Undead based on how they died before transforming, with blue-tones for those who choked to death when Red Queen changed the atmosphere, and ochre for those who drowned in the labs.
