Jonathan Strange and Mr. Norrell could return for Season 2.
While the BBC is billing the 19th century fantasy drama as a 7-episode ‘miniseries’, writer Peter Harness says he’d be more than willing to adapt a second season, should writer Susanna Clarke write a sequel to the novel on which the series is based, per THR:
This was a grueling undertaking. It was the longest shoot I’ve ever done. It brands you. There is an unseen bond between us and the material and between us and Susanna, who is the most incredible, imaginative author and yet reclusive and fascinating and interesting. Yes. I do believe there is more material in her mind. Who knows how much she’s written or what she’s written or whether she’ll ever publish, but if she ever does, you bet your ass we’ll be there.
