Lovecraft fans are quite vocal about their dislike for half-baked or totally erroneous interpretations of Lovecraft's visions. Hollywood has rightly taken the brunt of this critique. Amateur filmmakers usually avoid taking on stories that demand the recreations of Lovecraft's more elaborate creatures, instead focusing on tales that are driven by suggestions and atmosphere. I enjoy taking the other route. However, instead of burying myself in pictorial research on Cthulhu I just jumped into the creation of my puppet, opting to work as fast as I could, simply driven by my impressions of the character. The head sculpture in Chavant clay was not overworked. I added three eyes on either side, and stopped as soon as I thought I had captured the essence of the monster.
He does a great job of documenting every part of the build process, including this nicely done sculpt for the head.
Having grown up at the tail end of the stop-motion era I have a real fondness for the technique. It's fascinating to see Cthulhu brought to life as a traditional armature puppet.
