'The Good Wife' Bosses, Cast Preview Alicia's Big Decision

Co-creators Robert and Michelle King, as well as series stars Julianna Margulies and Christine Baranski also preview Kurt's return.

The Good Wife is bringing back Diane (Christine Baranski)'s husband, Kurt McVeigh (Gary Cole), during Sunday's new episode, and his ballistics expertise will immediately be put to the test.

"We're fascinated with the idea of 3D technology and how it's being applied to firearms, and how it's changing the rules of ballistics, which is what Gary Cole's character's day job is about," The Good Wife co-creator Robert King recently told THR.

"And Grace (Makenzie Vega)'s story, too. She's someone who has this religious component," Robert King added. "The bottom line is, what we love is when you make this decision for a character and it impacts everyone, not just one part [of the story]."

The Good Wife airs Sundays at 9 p.m. on CBS.
