Whenever a solid "brain trust" around creature assembly exists, then the process behind crafting these monsters must've been interesting. This 13-minute featurette captures the process of crafting the concepts for the monsters, from the models assembled for the primary ideas to the separation of computer and realistic tangible effects. KNB effects did some really strong work here, even in the small ways that purely give actors inspiration for their performances.
