The 'Les Miserables' star, who has adopted children Oscar, 12, and Ava, seven, with wife Deborra-Lee Furness, thinks parenthood has been one of the greatest gifts he could ever receive, reported Daily Star.
"I am an adoptive parent and I can't imagine there being any difference of intensity in emotion to being a biological parent. It is certainly one of the great gifts and it changes you from the inside for ever, so I can certainly relate," he sauid.
In "Les Miserables" Jackman, 44, portrays an ex-prisoner-turned-factory owner Valjean, who tries to help the poor as much as he can.
And the actor, who is backing the Global Poverty Project, is hoping the role can make him a better person.
"Valjean is one of the great examples to follow.
In no way do I really measure up to this man. But by playing him, hopefully it makes you a better person," he added.
