Russell Crowe believes he has changed since becoming a father.

The 'Water Diviner' star has eight-year-old Tennyson and 11-year-old Charles with estranged wife Danielle Spencer and has admitted he now sees everything through the ''prism of being a parent'', something which gave him a ''deep connection'' to the character he played in the film.

He said: ''You know, once you're a parent, everything that you do in life happens from the prism of being a parent.

''So obviously there was a deep connection for me when I read that particular story.''

The 51-year-old actor also admitted he found some of the scenes - in which his character's three sons were fatally wounded in the Battle of Gallipoli - particularly ''difficult'' to film.

He added to E! News: ''Shooting those scenes was very difficult to take emotionally.''

Meanwhile, Russell previously admitted he has become more empathetic and compassionate following the arrival of his two sons.

He said: ''I was in the middle of life, doing other projects, developing things, and suddenly this script (for 'The Water Diviner') arrived and everything changed.

''As a father of two sons, there was an empathy and compassion, straight away. So in a sense I felt I didn't choose the movie. It chose me.''
