Buster Keaton
The side-effects of war are atrocious and usually life-long. This was true for Buster Keaton who, after being sent to fight the Germans in France during WWI, returned home with his hearing damaged for life. But after his time in the 40th Infantry Division, he impressed the world with his genius silent films. It’s kind of ironic, isn’t it?
James Avery
Doing the voice of Shredder in the Teenage Mutant Ninja Turtles did not constitute as the military service of James Avery, but something else did. His real service to his country was during the Vietnam War between 1968 and 1969.
