Actor David Schwimmer was left devastated when he found two of his former girlfriends had been sexually abused as children.
The former Friends star directs new film Trust, about a mother and father discover their teenage daughter has been raped by a paedophile she befriended online.
Schwimmer has now opened up about his own experience dealing with abuse, telling Britain's Seven, "I've had two girlfriends who were victims of child sexual abuse. That sensitised me to the issue in a way that I hadn't been before.
"You want to find them (the attacker). In my girlfriend's case the abuser was a family member who was still around and I couldn't get my head around that. I told her that I had to know if I was ever in the same room as him because I wouldn't be responsible for my actions."
