Mamie Gummer Joins 'First Cut' And More Casting News

Mamie Gummer is trading the law for medicine ... sort of. Gummer, who was last seen on "The Good Wife" as attorney Nancy Crozier, will headline The CW's new medical drama pilot "First Cut."

According to TVLine, Gummer will star opposite "Smallville" veteran Justin Hartley as a formerly nerdy woman ready to shed her old persona. Gummer previously played doctor on ABC's short-lived "Off the Map."

"Gilmore Girls" veteran Jennie Snyder Urman wrote the pilot and "Pushing Daisies" alumnus Dan Jinks is executive producing it.
