WGN America did renew its Underground Railroad thriller “Underground” for a second season, so there’s more to come from the breakout hit series created by Misha Green and Joe Pokaski, which drew 3 million Total Viewers on Wednesday nights during its 10-episode first season run.

Produced by Sony Pictures Television and Tribune Studios, the 10-episode second season order is set for a 2017 debut.

Executive-produced by Misha Green, Joe Pokaski, John Legend, Akiva Goldsman, Tory Tunnell, Joby Harold, Mike Jackson, Ty Stiklorius and Anthony Hemingway, “Underground” follows a courageous group of American heroes who attempt a daring flight to freedom in the greatest escape in history.

The celebrated cast of “Underground” includes Jurnee Smollett-Bell as Rosalee, Aldis Hodge as Noah, Christopher Meloni as August Pullman, Alano Miller as Cato, Jessica de Gouw as Elizabeth Hawkes, Marc Blucas as John Hawkes, Adina Porter as Pearly Mae, Mykelti Williamson as Moses, Amirah Vann as Ernestine, Johnny Ray Gill as Sam, Chris Chalk as William Still, Reed Diamond as Tom Macon, Theodus Crane as Zeke, James Lafferty as U.S. Marshall Kyle Risdin, Renwick Scott as Henry and Jussie Smollett as Josey.

The season 1 finale air Wednesday, May 11, with quite a cliffhanger (the introduction of a character named Harriet – obviously implying Harriet Tubman), leaving fans anticipating what’s to come in the next season.

Although it really shouldn’t have been a surprise, assuming it was to you. The series is called “Underground” after all (as in the Underground Railroad; although the title has multiple meanings); so you would expect that, at some point, we would be introduced to the real-life American hero who is most often associated with that significant artifact.

Although how much of “Harriet” audiences can expect to see in the upcoming season (and potentially beyond) isn’t public information at this time. But, as Misha Green (series co-creator and executive producer) said in an interview following the season 1 finale, “She’s definitely going to be a character that’s going to be coming in and out of our series, for sure.”

2017 feels like a long time away, but time flies. So if you’re one of those who griped about your cable TV provider not carrying WGN America, you should know that “Underground” is now streaming on Hulu – the entire 10-episode first season. Of course you have to have a subscription to Hulu to watch, just like any other streaming service (Netflix, Amazon , etc). So if you do have one, you’re in luck. Binge-watch season 1 of “Underground” now. If you’re not a subscriber, Hulu, sign up for an account. They offer a 1-week free trial, so you can sign up, watch all 10 episodes within the week of your trial, and then cancel afterward! Or you can stick around for $7.99/month (with limited commercials) or $11.99 (no commercials).

Sorry, it’s not on Netflix or Amazon Prime yet.
