David G. Arkin (December 24, 1941 – January 14, 1991) was an American actor best known for his numerous supporting appearances in the films of Robert Altman. These roles were part of Altman’s frequent ensemble and included Staff Sergeant Major Vollmer in the 1970 film MASH (where he also wrote and voiced the PA Announcements), Harry in The Long Goodbye, Norman in Nashville, The Mailman/The Police Officer in Popeye. Arkin was known among his friends and colleagues for having introduced his friend Arnold Schwarzenegger (then Arnold Strong) to Robert Altman, at the time The Long Goodbye was being cast. This began Schwarzenegger’s career in film (a story re-told recently by Mitchell Zuckoff in his 2009 book Robert Altman: An Oral Biography).
