Washington, Nov 13 : American actress Angelina Jolie says that she had become pregnant with her twins, Knox and Vivienne, while she was filming Clint Eastwood's 'Changeling'.
Jolie played the part of real-life California woman Christine Collins, who fought the police when they mistook another boy for her missing son and refused to keep the search alive.
The Tomb Raider star revealed that the emotions involved in the movie led to her real-life motherhood.
"I got pregnant right in the middle of it (film) and, I think, partially because of it. I was so emotional about children that I think something kicked into gear," Contactmusic quoted her as telling the Los Angeles Times.
Jolie had given birth to her twins in Nice, France in July (08).
