Hugh Jackman ''hasn't changed'' despite becoming a worldwide icon.

'The Wolverine' director James Mangold - who first worked with the Australian actor on 2001 romantic comedy 'Kate & Leopold' - insist the 44-year-old star has the same ''humility'' and ''soul'' as he did when they first teamed up, despite Hugh going on to forge a hugely successful Hollywood career.

He told BANG Showbiz: ''I made another movie with Hugh and we're great friends, so it couldn't have been easier [to work with him]. It was a great experience working with again. He hasn't changed in the 12 years since we made our last picture. I say that wishing I had a better answer and could say he has!

''He has two children now and he's an international movie star now, but nothing about his soul, humility, hard work and discipline has changed. Not a thing.''

Meanwhile, Hugh - who has two adopted children, Oscar, 13, and eight-year-old Ava, with wife Deborra-lee Furness - has credited 'X-Men' director Bryan Singer for changing his life in 1999, when he was first cast as claw-wielding superhero Wolverine.

The 44-year-old star reflected: ''13 years ago Bryan gave me this role and changed my life. I'm forever grateful to him. I love playing Wolverine.''
