Richie is just the latest sibling fans will get to meet. Last season, Dr. Mindy's little brother, college student-turned-aspiring rapper Rishi (Utkarsh Ambudkar), appeared in multiple episodes. In Tuesday's episode (9:30/8:30c on Fox), Lost's Alan Dale will guest-star as Jeremy's dad.

In addition to his role in The Social Network, Minghella most recently co-starred in The Internship.
