As for previous series in the
Walking with... franchise, the computer graphics of
Walking with Monsters were created by the visual effects company
Framestore.
Walking with Monsters employed the most sophisticated CGI in the entire franchise, featuring 29 different creatures (more than in previous series) in almost 600 VFX shots. Though close-up shots in previous series had often been made with animatronics, more such shots were made with CGI in
Walking with Monsters owing to the extent to which computer graphics had improved by 2005. Models of animals were first made physically, based on fossil evidence, before being scanned and animated. Unlike the creatures featured in previous series, the animals in
Walking with Monsters were much less familiar to wider audiences and, according to producer and director
Chloe Leland, more "fantastical". The production team feared that this would make the creatures more difficult to believe in. To remedy this issue, the production team used various techniques, including adding numerous shots of the creatures interacting with the camera (such as a
Brontoscorpio shattering a camera lens) and using night vision in certain scenes to increase the sense of realism. The series was shot in
Super 16 and filmed over a 12-month period. Filming locations included
Arizona,
Florida and the
Canary Islands. Some detail shots of elements such as burrows, eggs and dead trees were built and shot in the studio. The production of
Walking with Monsters was envisioned as finishing the story of prehistoric life began with
Walking with Dinosaurs in 1999 and continued in
Walking with Beasts in 2001.
Dinosaurs focused on the
Mesozoic and
Beasts focused on the
Cenozoic, which meant that
Monsters completed the so-called "
Trilogy of Life". According to behind-the-scenes material from
Walking with Monsters, all three series together cost a total of £15 million to make. == Episodes ==
