Jurnee Smollett-Bell has confirmed plans for Underground Season 2 and beyond in an interview with Variety:
As you said, the Underground Railroad was extremely dangerous and chances are that many of the show’s characters won’t survive the first season. Have you talked about that and what this means if you were to get a second season?
JSB: It’s such a rich world and there’s so many stories we could pull from just because it was so dangerous. The risk that these men and women took, it really altered history. They have a lot of plans, if we’re so lucky, for the next few seasons.
Stay tuned as we continue to monitor the status of Underground Season 2 on WGN…
