For years he came to the aid of Hermione and Ron, and in a strange, real-life moment Daniel Radcliffe is also a muggle world hero.
The actor, famed for his role as Harry Potter in the film franchise, helped a scared tourist who was slashed across the face in a robbery by thugs who were riding a moped, the Evening Standard reports.
In the incident, which took place last Friday evening, the 27-year-old ran to assist a man who was targeted by two male attackers on Chelsea's fashionable King's Road, west London.
The two moped riders managed to steal the tourist's Louis Vuitton bag and left him with a facial injury.
It was a former police officer who first worked out what would happen and tried to prevent the attack.
David Videcette, who was driving around the area at the time, said he began to follow the men when he noticed that they were behaving oddly.
He witnessed the men pull a knife before speeding through a set of red lights. When he returned to the scene of the attack, he noticed Daniel Radcliffe assisting the injured man.
"It was a bit of a surreal moment," David told The Evening Standard. "I said, 'You're Daniel Radcliffe' and he replied, 'I am'.
"He was a really nice bloke; a lot of stars wouldn't have stopped to help.
"The victim was very, very shaken up."
David, formerly of the Metropolitan Police's counter-terror unit, said his attention was raised when he spotted the riders without number plates on their mopeds.
"I realised they were up to no good," he explained. "I decided to call the police and told them they needed to come and have a look. No sooner than I was on the phone to them that I saw one of them reaching for something in his waistband.
"I realised they were getting ready to do something. I cruised behind them in my car and they darted down a side street."
LADbible has reached out to Daniel's team for further comment but so far they have only confirmed that the actor was present at the scene.
David described that the tourist did put up a fight to protect his bag but the victim slashed him in the face with a knife.
Police said in a statement that they were called to an incident and that the victim was a man in his fifties. No arrests were made at the scene and enquiries are to continue.

The gangs use stolen scooters, mopeds, motorcycles and bikes to commit thousands of snatch offences.
Operation Venice is the Metropolitan Police's campaign to tackle moped crimes, with 500 known offenders in existence and some with 20-plus crimes to their name.
