QUATERmain NOT QUARTERmain!!
Just like in the Chamberlain movies, these moron actors can't even pronounce the protagonist's name correctly. Can't they read the script? And what's wrong with the director? (It reminds me of Stargate: SG-1, where there are at least six different pronunciations of "Goa'uld.")
If I remember correctly, John Rhys-Davies actually pronounced the name correctly toward the beginning of the 1985 movie, but then descended into the same mindless ignorance as the other actors.
