Some well known Hollywood icons that served in the US Military.

10. Rob Riggle, U.S. Marine Corps - While he's a comedian and comic actor known for his appearances on The Daily Show, The Hangover, Fox NFL Sunday, and as an SNL cast member, his military service is no joke. He joined the Marines in 1990 with the intent of becoming an aviator, but decided to pursue a comedy career instead. He stayed with the service as a reservist, however, and served as a public affairs officer. In this capacity, he would serve in Liberia, Kosovo, Albania, and Afghanistan. He retired after 23 years as a Lieutenant Colonel.
