Donald Sutherland as "Hawkeye Pierce" in M.A.S.H. made such an impression on when I saw this movie on its release as a very young teenager. I've pretty much never got along with authority since.
I watched the entire M.A.S.H series when I was young and it made a similar impression. I watched it before the film though, so my brain couldn't fathom anyone other than Alan Alda as Hawkeye.
Sutherland with Jane Fonda helped bring the anti-militarist anti-authoritarianism to actual soldiers in 1971....
> F.T.A. is a 1972 American documentary film starring Jane Fonda and Donald Sutherland and directed by Francine Parker, which follows a 1971 anti-Vietnam War road show for G.I.s, the FTA Show, as it stops in Hawaii, The Philippines, Okinawa, and Japan.[1][2]: p.143 It includes highlights from the show, behind the scenes footage, local performers from the countries visited, and interviews and conversations with GIs "as they discuss what they saw in battle, their anger with the military bureaucracy, and their opposition to America's presence in Indochina."[3] Called by Fonda "a spit and a prayer production" it was far from a big budget Hollywood movie, or even a well-funded documentary. While the movie "is raw," it "underscores how infectious the movement of the 60s and 70s was", and chronicles both the Tour itself as well as the soldiers who came to see it and "the local talent of organizers, labor unions and artist/activists" in the countries visited
