NBC is only showing the 13 episodes that were initially ordered.
The news of the stoppage in production follows the second highest rated episode for the series, which featured Jim Corrigan and The Spectre.
It's also been stated NBC is still considering a second season for Constantine.
Now, in what may be a sign Constantine may be getting the axe, series lead, Matt Ryan, has taken to his Twitter account to start a #SaveConstantine campaign.
Ryan directs supporters to tweet to the official NBC Constantine Twitter account as well as the official Facebook page, and to "keep watching."
It probably didn't help Constantine that NBC gave it a Friday night time slot. I actually wouldn't mind Netflix picking up this series and seeing an even darker approach (and smoking).
