the Make up

I found a discription via google.

First water based spray to seal the skin... Six colours to shade it..Petroleum Jelly, Talced, plastics and hot gelatin to give it that crusty look.. Took 4 hours to finish the job.. they then had to shoot in a hurry as the heat given off by lamps and Gambons body destroyed the makeup

Or you could read the trivia section.

Perhaps the OP just wants to reach out for some sense of community.
