Hugh Jackman as 'The Wolverine'

The 44-year-old actor may play the "cool" claw-wielding superhero in the 2013 blockbuster but he admits his 13-year-old son Oscar rarely speaks about his role and usually dismisses the idea that the hunky
star is anything like Marvel character.

Speaking on 'The Late Show with David Letterman', Hugh said: "He never talks to me about 'Wolverine'. He never admits it's cool, he never admits, 'This is great,' nothing like that.

"In fact a friend of his was saying how cool and he goes, 'Trust me, my dad is nothing like Wolverine, he's not tough, he's not cool in any way.' "

However, despite Oscar's apparent unwillingness to talk about 'Wolverine', the star admitted his son - who he adopted with his wife

Deborra-Lee Furness - jumped at the idea of joining him to watch the movie at 7am.

He explained: "I had to see the movie at 7am and I said, 'Oscar, I'm gonna see 'The Wolverine', I have to watch it in the morning.' Now this is summer vacation, there is no 7am for a 13 year old. Six o'clock in the morning, he was up, waking me up like 'Dad, is it time?

Is it time?'."
