Daniel Radcliffe was made incredibly rich at a very young age when he played Harry Potter in the immensely popular films.
However, he has admitted that he has barely touched his fortune, which is estimated by various rich lists to be around £74 million (NZ$130 million).
He told the Belfast Telegraph: "I don't really do anything with my money."
"I'm very grateful for it, because having money means you don't have to worry about it, which is a very lovely freedom to have. It also gives me immense freedom, career-wise."
Because he has saved his money, he feels free to act in independent films.
He told the paper: "I feel you have a responsibility when you can be that choosy.
"For all the people who've followed my career, I want to give them something to be interested in, rather than them just watch me make loads of money on c*** films for the rest of my life."
For him, a feeling money can't buy is his feeling on set.
The actor said: "If someone told me tomorrow, 'You're never going back on set,' I really wouldn't know what to do with the rest of my life. I don't know what my life looks like without regularly being on a film set.
"I'd go crazy. I'm one of the lucky few who loves my job."
Mr Radcliffe also spoke of the trials he has faced filming Imperium, in which he stars as Nate Foster, an FBI agent who goes undercover as a neo-Nazi in order to expose a terrorist plot.
He said: "When we filmed the rally riot scene, we only had one camera, so from a distance people couldn't see it; they just saw a Ku Klux Klan rally walking through their town.
"We had people who were very angry and we had to explain it was a film..
"We also had someone wind down the window, beep their horn and give a 'white power' (salute), so it was a very weird scene to shoot."
