19 Behind-the-Scenes Facts We Didn't Know About 'Kelly's Heroes'

Kelly's Heroes (1970) is praised by many for its depiction of World War II. Taking inspiration from the book by Ian Sayer and Douglas Botting, the movie centers around a heist carried out by German and American officers. The Guinness Book of World Records even recognized this event as the " Biggest Robbery Ever ."

Here are some fascinating behind-the-scenes facts about the iconic film.

Background of Kelly's Heroes (1970)

In 1945, as Allied bombers continued to pound Berlin , the Germans began moving assets south, for safekeeping; vast trainloads of gold and currency were evacuated from the country's capital. It's a mystifying story and one that caught the attention of Sayer and Botting. At the time of the original investigation, the fabulous treasure was estimated to be worth around $2,500,000,000.

It's also a story of an attempted whitewash in a US scandal that predated Richard Nixon and Watergate by nearly three decades. Investigators were impeded every strep of the way as they struggled to uncover the truth, and they were left fearing for their lives.

The authors' quest led them into a murky, dangerous post-war world of racketeering, corruption and gang warfare. Their brilliant reporting, matching eyewitness testimonies and declassified top-secret documents from the American archives lay bare this monumental crime in a narrative throng with SS desperadoes, a red-headed queen of crime and US military governors living like kings. Also revealed is the authors' discovery of some of the missing treasure in the Bank of England.

Now, let's take a look at some bizarre trivia from the fantastic film that is Kelly's Heroes .

Donal Sutherland nearly lost his life while filming

While filming in Yugoslavia, Donald Sutherland , cast as Sgt. "Oddball," was struck by spinal meningitis. This particular strain, like many others, carries the risk of death due to inflammation of the membranes surrounding the spinal cord and brain.

Sutherland's wife was urgently summoned to Yugoslavia via telegram, accompanied by the grave warning that her husband may not survive until she got there. Thankfully, he managed to overcome the illness and continues to be involved in his acting pursuits.

Things change during the editing process

Scenes often undergo reordering during the editing process, as directors realize certain parts may fit better earlier or later in the film. This was the case for Kelly's Heroes . Observant viewers of the film may notice that when Clint Eastwood 's Pvt. Kelly visits Staff Sgt. "Crapgame," he brings him a bottle of whiskey. Later on, when Kelly visits Don Rickles ' character, he is given the exact same bottle.

It's probable these scenes were swapped during editing, suggesting the initial plan may have been for the second scene to occur earlier in the movie.

Donald Sutherland's wife was arrested for aiding the Black Panthers

During his time in Yugoslavia, Clint Eastwood told Donald Sutherland that Sutherland's wife, Shirley, had been taken into custody for trying to purchase grenades for the Black Panthers, a far-left political group. She had attempted to make the purchase using a personal check, but the person she was negotiating with turned out to be an undercover FBI agent.

Sutherland recalls that when Eastwood mentioned the personal check, he burst into laughter so hard that he collapsed and needed help to stand up. Eastwood then assured his friend that he would fully support him in this situation.
