military celebritiesIn honor of Military Families Week, AOL salutes the movie stars who've served our country, many of whom -- like George C. Scott and Henry Fonda -- also starred in the most famous war movies of all time.

Clark Gable enlisted at age 43 after losing wife Carole Lombard to the war effort, but some stars, including Ronald Reagan and Jimmy Stewart, were already in the service when the U.S. entered World War II. Others, like Gene Hackman and Harvey Keitel, served before becoming famous. (And both left home early to join up.)

Join us in paying tribute to these famous veterans, who weren't just acting when they portrayed men in uniform.
