Hugh Jackman credits playing rugby with saving him from trouble as a teen.

The X-Men star, who is famed for his friendly demeanour, reveals he would often explode into fits of rage during his formative years, until he learned to release his negative energy on the rugby pitch.

He tells Empire magazine, "As a teenager I was explosively angry. I think rugby saved me, because that's just organised violence. I would have got in a lot more fights. But I was someone who would go into a little bit of a blind rage and it was not pretty."

Jackman admits he still struggles with his temper at times, but keeps his anger under wraps for the sake of his young kids, Oscar and Ava.

He adds, ''I think, just naturally, I started to calm down. Or I just made the choice to be a little bit less volatile. But as I got older there were fewer moments of that explosive rage. But even to this day they're still there, and I probably am just better at (controlling it) or it's just longer in between. But it's still there and I have to work on it and I have to be very sensitive as a father - I don't want them seeing that. Sometimes, of course, I lose it, but it's not constructive. And it really unsettles kids, I think. I do work on it.''
