Glenn Larson's concept of the lead character's ability to manifest into the body of an animal stalker posed creative solutions to the production team. Using a "really alive black panther cat", or a "bird", or a "snake", for the actor's transition, was a study in discipline for cast and crew. The production designer was required to coordinate, with the director, set decorator, stunt supervisor, the cat's wrangler, and with the actor, every instance the script's action motivation occurred using any of the animal(s) involved. Location filming was most difficult, whereas within the stage environment, this allowed a more controlled environment to use the beasties! When a cobra snake was required in one script, the entire set's perimeter floor and wall had to be sealed preventing the cobra's escape. A barricade low (2'-0") wall placed in the open end of the set in order to seal the entire stage set environment to secure the staging area. The camera crew lifting their equipment into the interior of the setting to just set up to film the action with the snake. The snake's trainer, "wrangler", supervising the required snake's movement and directed motivation within the reach of control.
