Pinewood Studios shooting some scenes on location at Wexham Park Hospital, Slough, Berkshire, UK over several nights and in Calgary, Alberta, Canada. Bob Keen and his crew had two months to play around with ideas before doing any modeling work. They used computer-controlled animatronics but only where necessary. Towards the end of principal photography, Barker brought Star Wars concept artist Ralph McQuarrie in to paint mattes for the Necropolis sequences and design the history of the Breed in a symbolic way on an enormous mural across a 60-foot space on the set at Pinewood to be used in the opening credits.

Elfman said of his score: "Once again it was time for me to stretch out... Combining dark/fun/sweet/tribal all into one.
