Trivia / Mackenna's Gold

  • Fake Nationality: Omar Sharif (an Egyptian) and Keenan Wynn (of Jewish-Irish background) as Mexicans; Julie Newmar (of Swedish-French descent), Ted Cassidy, and a few other obviously Caucasian actors as Apache Indians (hidden under layers of brown makeup).
  • Paying Their Dues: The making of this movie was documented in a short film directed and written by a young film student named George Lucas.
