Al Pacino believes fatherhood is a "mini miracle"

He told People magazine: "It's just so wonderful to have children. For me, I loved it.

"It changed me for, if you want to say, the better. It changed me for life. And the idea that you're throwing your focus on other humans who happen to be your children ... there's the love."

Asked how fatherhood feels different this time around, he added: "Well, it's always the same. It's always the same. It's a mini miracle. That's all I can say.

"I love it, I'm very happy that I see my children. It's great."

The 'Scarface' actor - recently admitted he wants to "stick around a little longer" for the sake of his young son.

He told the New York Times newspaper of his little boy: "He's come into the world a little more now. He's learning things."

Asked if writing his story in his own words for Roman was one of the reasons for writing his new memoir, 'Sonny Boy', he added: "That's one of the reasons, of course. And that has been a campaign for me to stick around a little longer if it's possible."

But the 'Godfather' star isn't sure if his own advancing years was a motivation for having another child.

Asked if it is possible "that having a child at 83 years old is a reaction to the recognition of your own mortality?", he replied: " Wow, that was something. I have to really think about that. I don't know. Maybe? I don't even understand it."

However, Al admitted having his young son has given him a "different" perspective on life.

He said: "When I saw the little baby there and the way he was just - you look at it differently now. You look at it like, what is this? This is so amazing!

"That's why I was so excited by hearing the Big Bang. Because I thought, I'm not gonna die!

"I don't mean literally. I mean spiritually. There's something out there that's bigger than us! You can't say 'better', because you don't really know, but something's out there going on that's more than we understand."
