Fall TV Preview: 'The Good Wife'

By

Julianna Margulies returns this year for a fifth season of the award winning political drama, CBS' The Good Wife, and things are apparently about to get "explosive" -- somehow.

"There's something incredibly profound about to happen to one of our characters, I say profound, because that will sort of make you all not know what it is."

While Margulies struggled to keep the details of the upcoming season sealed away, she did let it slip that there would be tension between the two law firms that "allows our characters to leave each other and then come back to each other in a great way."

PICS: Star Sightings

As far as guest stars, expect Nathan Lane (The Producers) and Michael J. Fox (if NBC agrees) to reprise their guest roles on the series.
