He added: "I was volatile. My mum left when I was eight. My anger didn't really surface until I was 12 or 13.
Hugh Jackman has opened up about a painful experience in his childhood.
The actor, who has been promoting his new film Peter Pan, admitted he feels a special bond with the titular boy who never grew up.
Jackman, who takes on Peter as Captain Blackbeard, revealed his mother left him when he was eight years old.
Asked if Peter was special to him because of their shared upbringings, he said: "Yes. (But) I was more sensitive about its connection to my two adopted children.
"In scenes at the orphanage in the beginning of the movie, the nun talks harshly: 'Your mums are not waiting for you. You're not going to see them again.'
"I actually read this to my wife and talked to (director) Joe Wright about it. I went, 'Hang on. This is dealing with adoption and orphans. I want to make sure that this movie is not something my kids are going to feel weird about.' "
Jackman admitted he was "fearful" and "felt powerless" from the moment his mum left, and revealed he was "volatile" once he reached his early teens.
"It was triggered because my parents were going to get reconciled and didn't. All those years I'd been holding out hope that they would."
Meanwhile, the star recently revealed he turned down the role of James Bond in the past - but would "seriously consider" it now, reports the Daily Mirror.
