We haven't heard much since then, but it turns out that reason is because Kreisberg was busy getting Arrow together for the CW.
Now that Arrow is underway, Kreisberg can turn his attention back to Booster Gold and tells IGN he'll have a script ready in a couple weeks.
I got a little waylaid by Arrow. Booster Gold is going in in the next couple weeks before Christmas. We'll see what happens from there. It's such a different project even though they're both DC Comics properties. Booster is much more candy and popcorn, being about time travel and changing the future and being a superhero who can fly. But they're both super-fun projects. As a lifelong DC Comics fan, I am beyond blessed to be working on these projects with all these amazing characters.
Last time we saw Booster Gold on TV was in episodes of Smallville, what does SyFy hold for the time-travelling super hero?
