Russell Crowe, star of 'Gladiator,' donates thousands to save a stuntman's leg.

Russell Crowe, star of "Gladiator," is assisting his friend in an attempt to preserve his leg.

According to Kennedy News and Media, a stuntman named Charlie Allan, who worked on "Gladiator," experienced a "crunching" sensation all the way down to his ankle when he fell off the top of his garage entrance while renovating it.

Allan, 61, may lose his leg due to the fall. Crowe, who worked with him on "Gladiator" and "Robin Hood," donated £5,000 ($6,336) through Allan's GoFundMe page.

Russell Crowe's donation makes me feel humbled and grateful, as we go back to our time together in "Gladiator." In that film, I was both a stuntman and actor, portraying the character who shouts at Russell with a severed head in my hand at the beginning of the movie.

"Seeing this scene always gives me goosebumps. With 15,000 men on set, it took three weeks to film the first 10 minutes of 'Gladiator.' This is how Russell and I became friends. We've been friends for years."

Allan's fall resulted in a "complete arterial thrombosis in his left leg, leaving him in a critical condition due to insufficient blood supply to his limb," according to Kennedy News and Media.

A blood clot that forms in an artery, known as arterial thrombosis, can be life-threatening as it can impede or halt the blood flow to vital organs such as the heart or brain, according to the NHS.

Allan was admitted to the University Hospital Hairmyres in Glasgow and informed that he required a procedure to mend his leg, according to Kennedy News and Media.

Allan was informed that his planned surgery couldn't go ahead due to previous blunt-force trauma to his leg, which caused his leg to turn white and go numb.

According to the outlet, he was discharged with painkillers and blood thinners and informed that no further surgery was possible under the NHS.

In an attempt to save his leg, Allan's wife, Chara Gallos-Allan, 33, started a GoFundMe page after hearing the news.

The objective of the GoFundMe campaign was to raise 25,000 euros (approximately $26,500) to cover the cost of an endovascular thrombectomy outside the U.K.

Allan expressed his excitement and humility about the possibility of undergoing the procedure. If he completes it before Christmas, he will have an active and outdoorsy holiday season.

"I'm in good shape for my age. I enjoy cycling and horseback riding. It's important to stay fit."

Charlie explained to the news outlet how the fall has severely affected his life.

"I can only walk 20 feet before the pain becomes unbearable, as I'm always on my feet for my events charity and teaching lads sword work for TV appearances," he stated.

"As an actor, stuntman, and combat stuntman, my profession has significantly affected my life. I am unable to keep up with my son as he grows older, and this has negatively impacted my quality of life."

Allan mentioned that he hasn't had the chance to watch "Gladiator II," starring Denzel Washington, Paul Mescal, and Pedro Pascal, but he plans to see it as soon as possible.
