Jolie's character in 'Changeling' reminded her of late mum

London, May 21 : Angelina Jolie had an emotional ride during the filming of her newest movie 'Changeling' because her character reminded her of her late mother.

The actress plays the role of a mother whose nine-year old son goes missing in the film directed by Clint Eastwood.

The 'Tomb Raider' star, who is pregnant with twins, said it "was a way to kind of revisit my mother after (her) passing".

Jolie's mother, who died last year, was "very sweet," she added.

"But when it came to her children she was a lion," BBC quoted her, as saying.

Jolie, 32, said she could not "imagine anything worse" than losing a child and had tapped into her own "pain and frustration" in playing the role.
