The first trailer for the upcoming Superman prequel Krypton has arrived. The series will debut on Syfy on March 21, 2018. Executive producer David S. Goyer stated that there will be a time travel element to the show and it means the show is not a part of DC comics “canon,” suggesting the show (if it’s successful) could branch out Seg-El’s long life across multiple series, Goyer stated,
You can tell [from that trailer] that time travel is involved, and what that means is history could be changed, and what happens in this show could be very different from the backstory that people know. A lot of people know that Krypton blows up and that’s what caused Superman to come to Earth, but this is really an untold story.
He’s an unlikely hero. He’s the unlikely choice of shouldering this burden of trying to stop someone from the present trying to prevent this Superman legacy… Adam Strange is a character that doesn’t really embody what Superman does as far as honor and justice, doesn’t really know right from wrong, but looks up to Superman.
