The Emmy-nominated Mad Men alum will appear in Season 6 as a brilliant, sophisticated and sensitive physician who helps Diane through a crazy time. "We couldn’t be more excited to have the enormously talented, usually-too-busy John Slattery join the cast,” said The Good Fight co-creators and showrunners Robert and Michelle King in a statement. “We feel like we’ve been chasing him forever.”
