The Filthy Thirteen

We’ll start by looking at the real-life group that inspired The Dirty Dozen‘s source material. Known as the “Filthy Thirteen,” they were part of the 1st Demolition Section, Regimental Headquarters Company, 506th Parachute Infantry Regiment, 101st Airborne Division during World War II.
The group earned their distinctive moniker while stationed in England, due to their habit of bathing no more than once a week. Once in mainland Europe, they were tasked with sabotaging enemy targets behind the lines. Their engagements included D-Day and Operation Market Garden.
Jim Brown retired from the NFL while filming The Dirty Dozen

Jim Brown, known both as a football star and an actor, portrayed Robert T. Jefferson in The Dirty Dozen. Although he enjoyed working on the film, it created tensions with the National Football League (NFL).
The extended filming schedule jeopardized his attendance at the 1967-68 season training camp. As the conflict grew, Cleveland Browns owner Art Modell warned Brown of fines and suspension if he failed to report to camp. Brown’s reaction shocked everyone—he held a press conference to announce his retirement from football.
Now that’s a bold move!
Donald Sutherland almost didn’t appear in The Dirty Dozen

It’s hard to imagine anyone other than Donald Sutherland portraying Vernon L. Pinkley in The Dirty Dozen, but that was almost the case! He was actually the second person cast in the role, with the original actor dropping out last minute because he felt the part was beneath him.
We bet whoever it was regretted their decision, considering how popular the movie was (and still is).
One of the largest sets ever built

The French château in The Dirty Dozen looks impressive, but did you know it was one of the largest set pieces ever built? Designed by art director William Hutchinson and a team of 85 workers, the structure was 240 feet long and 50 feet tall. To make it look even more realistic, landscapers added six weeping willows, 450 shrubs, 30 spruce trees, 5,400 square yards of heather, and 400 ferns.
The château was built so strong that it would have taken 70 tons of explosives to bring it down. Because of this, the crew made a lighter version out of plastic and cork for the scene where it was blown up.
Serving as an anti-war allegory for Vietnam

Although The Dirty Dozen is a war movie, director Robert Aldrich intended it to serve as an anti-war allegory for the Vietnam War. as was the intention of director Robert Aldrich. This is evident in the film’s anti-military and -authority tones.
Released when the United States was deeply involved in the Vietnam conflict, the film is widely regarded as one of the earliest public critiques of the war, even though it is set during World War II.
Lee Marvin’s alcoholism was a major problem during filming

It’s well known that Lee Marvin struggled with alcohol throughout his life, and his drinking became a serious issue during the filming of The Dirty Dozen. Many believe his struggles were linked to his wartime experiences, as he served with the U.S. Marine Corps in the Pacific Theater during World War II.
In one scene, Marvin’s character, Maj. John Reisman, was supposed to drive an armored truck while Joseph Wladislaw (Charles Bronson) sat in the passenger seat. However, when it was time to film, Marvin was nowhere to be found. Crew members eventually located him at a pub and brought him back to set, where they gave him coffee in an attempt to sober him up.
Upon his arrival, Bronson came up to him and said, “I’m going to f*****g kill you, Lee.”
John Wayne as Maj. John Reisman?

Just like Donald Sutherland, Lee Marvin wasn’t the original choice to play Maj. John Reisman in The Dirty Dozen—another Hollywood legend was first offered the role. Curious who it was? None other than the Duke himself, John Wayne!
Wayne, well-known for his performances in war films like The Longest Day (1962) and The Alamo (1960), ultimately declined the part due to his personal principles. The actor didn’t approve of the character’s affair with an enlisted man’s wife while her husband was serving overseas.
Moreover, Wayne opted out to focus on a project intended to rally public support for the Vietnam War, as American enthusiasm for the conflict had begun to decline at that time.
Several members of the cast served during World War II

As with many military movies released in the post-war era, The Dirty Dozen featured a number of veterans:
- Lee Marvin, US Marine Corps – He saw action as a scout sniper and was injured during the Battle of Saipan.
- Robert Webber, US Marine Corps – He served as a 776-Radio Operator (Low Speed) in Guam and on Okinawa.
- Charles Bronson, US Army Air Forces – He flew 25 combat missions over Japan aboard a Boeing B-29 Superfortress.
- Ernest Borgnine, US Navy – He was dispatched to the Atlantic coast aboard the patrol yacht USS Sylph (PY-12).
- Telly Savalas, US Army – While never deployed overseas, he was stationed out of Camp Pickett, Virginia from 1941-43.
- George Kennedy, US Army – He served under Gen. George Patton and saw action during the Battle of the Bulge.
- Robert Phillips, US Marine Corps – He was a self-defense instructor with the service throughout WWII.
- Clint Walker, Merchant Marine – He quit school and enlisted in the Merchant Marine when he was just 17 years old.
- Robert Ryan, US Marine Corps – He served as a drill instructor at Marine Corps Base Camp Pendelton, California.
- Richard Jaeckel, Merchant Marine – He enlisted close to the end of the war and remained with the service until 1949.
- Ralph Meeker, US Navy – He only served for a few months before being discharged for an injured neck.
Four of the actors reunited over 30 years later

It’s rare for two actors to reunite on a later project—so having four come together again is almost unheard of. But that’s exactly what happened 31 years after The Dirty Dozen hit theaters. Ernest Borgnine, Clint Walker, George Kennedy, and Jim Brown all returned to voice characters in the 1998 movie Small Soldiers, directed by Joe Dante.
The film tells the story of action figures that come to life after being equipped with advanced military microchips. Think Toy Story (1995), but with a darker, more grown-up twist.
From The Dirty Dozen to M*A*S*H

As aforementioned, Donald Sutherland portrays Vernon L. Pinkley in The Dirty Dozen, but did you know that the role is the very reason he was cast in 1970’s M*A*S*H? It’s true!

The scene where Pinkley pretends to be a general to inspect Col. Everett Dasher Breed’s (Robert Ryan) troops wasn’t intended to feature the character. It was initially written for Clint Walker, but the actor felt too uncomfortable and it was given to Sutherland. It’s said this scene was the main reason why the Canadian actor was given the role of Benjamin “Hawkeye” Pierce in M*A*S*H.
