The 'Prisoners' star - who was rumored to have been offered a $100 million deal to play his Wolverine character across a number of movies - doesn't want to be perceived as greedy, and is conscious about how much money he makes compared to normal people.
Hugh told The Times newspaper: "I've got more than I need, for sure. There's no doubt.
"When does it become gluttony? And is there a point when you say, 'That's enough! Give the rest away!' I'm a little embarrassed by it and a little uncomfortable with it.
"I struggle with it and what effect it will have on my children growing up".
The 44-year-old Australian actor - who has son Oscar, 13, and eight-year-old daughter Ava with his wife, Deborra-Lee Furness - has played a diverse range of characters in musicals, dramas and action films, but only recently feels he has been accepted as a "proper" actor, after he was nominated for an Oscar for his role in 'Les Miserables' and invited to a luncheon with other nominees including Daniel Day-Lewis, Robert DeNiro, Tommy Lee Jones, Alan Arkin, and Joaquin Phoenix.
Explaining the dinner, he said: "It was a little awkward at first but within 15 minutes, after a couple of beers and a few wines, everyone just relaxed, and it became everything that I will never forget".
