Isto foi abordado em uma entrevista com o escritor / diretor do filme, David Twohy. Riddick inicialmente salvou o cão por razões puramente egoístas, mas acabou gostando e respeitando-o como um companheiro.
This was a little odd because the hero baddie creature, we call them Mud Demons in our production circles. Nobody calls them that in the movie. Those were actually designed by Patrick Tatopoulos, who was my creature designer on Pitch Black and who is now a production designer of note.
And then when it came to jackals, Patrick gave us some early sketches, and those were refined by other artists, because a pet jackal in the story that he finds is a puppy. At first he was using it as a tool to help inoculate himself against these Mud Demons. But then the puppy grows on him and grows literally and figuratively on him. And it becomes his companion on this world. So, at that point it went through a series of design evolutions, including with the creature house up in Montreal who did the CG work. But yeah, you are still building some fabricated pieces, not animatronics, that try to emulate life by blinking. But if Riddick has to, in a close-up, touch the animal's hide and run his fingers through it, then certainly that will be a build piece you can physically touch. But anytime it's the full grown jackal, or you need a face along with Riddick running and jumping, forget it. It's CG now
