Sure, so for the skin walker, which is heavily inspired by the werewolf lore, of course, kinda blended them a little bit. I just want to bring up, Jim Beinke, who's the special effects designer on the film, we met two and a half years before filming began, maybe three years, and he was in love with the script and was so excited about, I mean, the skinwalker was his baby. I mean, I had the look that I wanted for it but he put his own twist to it and I can't thank him enough for what he created here. And also, the actor who portrayed the skin walker Steven Flores also did a phenomenal job, just the amount of difficult things he had to go through to portray him was crazy, but in terms of the special effects, Jim had quite a large team that helped him throughout the process. I think we started doing prosthetics two years in advance on Steven, molds and etcetera, it took awhile. In terms of the blending of the visual effects and practical effects, we realized in post-production that the transformation aspect of, from human, there were three stages of transformation, so from the transformation aspect of the regular to the full beast, I personally felt that it wasn’t fully clear and people who watched the film were a little bit confused as to how that thing, where that big beast came from, so I just had to clarify that in a CGI shot of him transforming. If not, I mean, the skinwalker is practically all practical effects, if we did anything to it, it was just adding eye glare in one or two scenes just so you could see his eyes when he's further away, but that's it, he's all practical and Jim Beinke is responsible for that magic behind it.
