The life-imitating-art incident saw the 41-year-old actor jumping to the rescue of a Deliveroo cyclist, who was being attacked by four men.
According to British reports on Friday (June 1), the gang attacked the cyclist and even smashed a bottle on his head.
Meanwhile, Mr Cumberbatch, who was riding in an Uber with his wife Sophie Hunter, jumped from the car and intervened.
He then dragged the four men off the cyclist, and was almost punched by the men, but managed to dodge the attack.
The Uber driver, who was taking Mr Cumberbatch and his wife to a club, said: "The cyclist was lucky, Benedict's a hero.".
As the car was about to turn into Marylebone High Street, they saw four guys pushing around a Deliveroo cyclist, said Mr Dias.
It was only after Mr Cumberbatch yelled at the group that Mr Dias realised it was the Doctor Strange actor. »
