Miller, 31, joins Becki Newton and Scott Foley on the series, about three siblings who reconnect following their father's death. He leaves them his vast fortune — but only if they agree to his unusual terms. Miller will play the youngest offspring, Jimmy, a thief just out of jail who is big on heart but lacks impulse control.
Before The Goodwin Games, Miller played a similar role in another Fox comedy pilot that was not picked up — Little Brother. He has appeared in Cloverfield, Our Idiot Brother and She's Out of My League. Lacy previously starred on ABC's short-lived Better With You.
