Matt Bomer already knew Derek Simonds, the creator and showrunner of The Sinner, before being approached about starring in the third season of the Netflix series.

"I had met with Derek years ago when he was involved in Call Me By Your Name, and we'd hit it off creatively and had a great conversation," Bomer, 42, says from his home in Los Angeles during an appearance on an episode of the Variety and iHeart podcast The Big Ticket.
