Most amusing was seeing actors who never served....

They were also older and had to serve their National Service, which had fewer exemptions; not to mention Caine and Connery were from poor backgrounds. Hackman was of an age for military service before the escalation of Vietnam.

The point acting is to tell a story via performance. A good actor doesn't need to have served in the military to give a good performance as a soldier. If he has a good imagination, has done his homework and listens to the military advisors, he can deliver just as convincing a performance as an actor who is a veteran. Despite having served in Korea, I still don't think Michael Caine convincingly handles weapons in all of his movies. Schwarzenegger served in the Austrian army and has never looked like he knew what to do with a rifle, except strike a pose.

Dirk Bogarde also served for 5 years in the Queen's Royal Regiment as an officer during WWII. He served in the Air Photographic Intelligence Unit and eventually attained the rank of major.

Alec Baldwin played a pilot in a movie once.

As the anti-John Wayne brigade are kicking up a stink again, perhaps they would like to peruse a couple of links.

John Wayne’s application to the O.S.S. On page twenty-three in a Los Angeles Times Magazine article dated September 21, 2003 Coming Soon: Living History On Exhibit are photos of two pages of at least twelve of Wayne’s August 2, 1943 application SA-1, page eleven marked in red pencil at the top “22087.” There is no doubt it is Wayne, he uses his birth name of Marion Robert Morrison, his middle name being changed to Mitchell after the birth of his younger brother Robert and his next of kin is listed as his then estranged wife Josephine Morrison with Mrs. John Wayne in parenthesis. Here for the first time is the first hard evidence that Wayne volunteered for potentially dangerous service with the equivalent of today’s C.I.A., and the papers are not out of someone’s attic, but official government documents.

Los Angeles Public Library, Los Angeles, California:
John Wayne's application for employment with the Office of Strategic Services (OSS), forerunner of the Central Intelligence Agency (CIA), August 2, 1943. Wayne applied for, but did not receive, a commission with the OSS during World War II. National Archives and Records Administration, Records of the Office of Strategic Services.

It appears that John Wayne actively inquired about military service in John Ford's photographic unit, but that's about it. He didn't really push the idea very much or he would have gone in earlier with John Ford and the others. He was worried about his career, first and foremost. Jimmy Stewart and Clark Gable didn't seem to be worried about their careers that much. There was too much else bigger at stake at the time, bigger than their individual wants and desires. Their careers didn't suffer after coming home. And they didn't have to fight personal demons and critics over not serving.
