The former Royal Shakespeare Company actor Hugh Keays-Byrne passed away at the age of 73. The Australian native starred as two unforgettable bad guys in the Mad Max franchise. First, Keays-Byrne played Toecutter in the original Mad Max movie. Most recently, he played the villain Immortan Joe in Mad Max: Fury Road. Keays-Byrne can attribute his role in both movies to a long-lasting friendship with director George Miller.
I was unable to find out what the actor died from.
