Miguel Ferrer,  NCIS: Los Angeles  -  When  Miguel Ferrer  passed away in his home on January 19, 2017 after a battle with throat cancer, his illness had allowed the writers on  NCIS: Los Angeles , which he&#39;d recurred on for two seasons before becoming a series regular in season five, to make a plan for his character, Owen Granger. Much like the man who portrayed him, it was revealed in season eight that Granger was dying of throat cancer, too, potentially as a result of exposure to Agent Orange.
