Hugh Jackman says having children changed him forever.
The 'Les Miserables' actor - who has adopted children Oscar, 12, and Ava, seven, with wife Deborra-lee Furness - believes taking on the care of a child gives a parent exactly the same bond as having a biological family and thinks parenthood has been one of the greatest ''gifts'' he could ever receive.
He said: ''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 forever, so I can certainly relate.''
In 'Les Miserables', Hugh, 44, portrays 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 and is a partner in a fair trade coffee company Laughing Man, is hoping the role can make him a ''better person''.
He added in an interview with The Sun newspaper: ''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.
''Certainly in the book [which the film is based on], what he does with the factory is not just helping people out but also giving them life and purpose. That's why I started that coffee business because, to me, it is a way to provide employment. A successful business is good for everyone.''
