Last week, a new NBC pilot had cast its lead actor, and now the rest of the cast is starting to come together. According to The Hollywood Reporter, Bill Pullman has signed on to start in the pilot Nathan vs. Nurture.

The pilot revolves around Harrington's character, an overachieving heart surgeon who meets his biological father Arthur (Pullman) and underachieving brothers 35 years after he was adopted. It was said that Arthur's excessive praise and coddling of his children could've lead to their unsuccessful lives.

No production schedule was announced for the pilot.
