Ok it was called 'Our Father'
Another similar one was called 'The man with 1000 kids'
And I just found a movie that took that as a plot called 'Delivery Man' based on French-Canadian film 'Starbuck'
However for the most part Epsteins appetite was just to get off to young girls, take pictures of them naked and stick them in his 'trophy room' I don't think he intended for them all to get pregnant, tho Virginia said he never wore a condom. He did ask her about birth control which, I think she was on. She was just 17 at the time she met him and stayed with him for 2 years. He bought her an apartment and paid her under the table. She only escaped by marrying a guy in Thailand she'd only known for 10 days. He'd sent her to Thailand after promising she could go there to study massage. She never finished the course.
All of his encounters with young girls started off as a massage. It was a way to already be naked with the girls, then he'd ask them to take their clothes off too, and because he was paying them, they did what they were told. You could say those girls were stupid, but most of them came from homes where they needed the money or were used to being molested.
