Hollywood is in mourning this week after the death of R. Lee Ermey, best known for his role in “Full Metal Jacket.” He was 74 years-old.

His death was confirmed by his manager, Bill Rogin, who said he passed away due to complications from pneumonia.

“It is a terrible loss that nobody was prepared for,” wrote Rogin. “He has meant so much to so many people. And, it is extremely difficult to truly quantify all of the great things this man has selflessly done for, and on behalf of, our many men and women in uniform.”

Ermey built a career for himself often playing military-type personalities on the screen. What many don’t know is that Ermey himself was a former Marine Corps drill instructor who was in the service for 11 years!

Ermey was nominated for a Golden Globe Award for his role in “Full Metal Jacket,” and some of his other famous credits include “Mississippi Burning,” “Prefontaine,” “Dead Man Walking,” and the remake of “The Texas Chainsaw Massacre.” In addition, he voiced the  Army green solider from “Toy Story” and had voiced roles in “SpongeBob SquarePants.”

“He has also contributed many iconic and indelible characters on film that will live on forever,” wrote Rogin. “Semper Fi, Gunny. Godspeed.”

The U.S. Army tweeted a tribute to Ermey, writing, “Rest In Peace, Gunny. We are grateful for your service to our country and for supporting our servicemembers. Semper Fi.”

Rest in peace, R. Lee Ermey! You will be dearly missed. Please say a prayer for Ermey’s family during this difficult time!
