Showtime recently renewed The Big C for a fourth and final season. The dramedy, which stars Laura Linney as a suburban wife and mother with cancer, will wrap its series run with four hour-long installments in 2013.

Created by Darlene Hunt, The Big C debuted in August 2010 and drew the largest audience for a Showtime original premiere in eight years. Showrunner Jenny Bicks, formerly a writer on HBO’s Sex and the City and a cancer survivor herself, sat down with World Screen Weekly to discuss the series in this video interview. Among other topics, Bicks talks about the delicate balance of finding humor within the show’s dramatic subject.
