Given IMDB's usual unreliability, this should probably be taken with a grain of salt, but the following names have now been attached to the His Dark Materials film:
Leif Einarsson – previz artist
Robert M. Kalafut – previz artist
Monty Simons – stunt coordinator (pre-vis, motion capture sequence)
Chris McClintock – research coordinator
