Former Friends star David Schwimmer was stunned to find many sex predators are family men while researching his creepy new movie Trus out.

The fact is that they are teachers, they are coaches, they're priests,they're professionals

The actor directs Clive Owen and Catherine Keener in the harrowing filmabout a teenager lured to a motel for sex by an online predator old enough to be her father, and he trawled through Fbi records to learn more about the sick minds he was dealing with.

But he didn't expect to find fathers and husbands in among the sickos prowling for sex with minors in cyberspace.

Schwimmer, who is a longtime activist with the Rape Foundation in SantaMonica, California, says, "A lot of these guys are married, have families. It's more frightening than the predator that's usually depicted in films, which is this weird, greasy loner that lives alone or with mum. "The fact is that they are teachers, they are coaches, they're priests,they're professionals". Playing the role of the girl's father in the film really hit home for British actor Owen, who has two daughters of his own. He adds, "I found it deeply upsetting, just as an idea.

I think something like that happening to your daughter is like a death of some kind".
