Coming off rumors that Nathan Fillion's Guy Gardner was set to make an appearance in the upcoming Lanterns series following his debut in James Gunn's Superman, we got confirmation back in March that the Firefly alum will indeed be a part of the HBO series.

Now, we may have our first look at Fillion's returning Green Lantern via a leaked promo standee.

We're not certain that this is actually from Lanterns, but the in-universe advertisement for an Electro-Punch energy drink was not part of Superman's marketing campaign. It could simply be something that wasn't used for the movie, but if it is Lanterns-related, it doesn't look like Guy has made many (any) changes to his divisive costume.

Fillion spoke about his take on the notoriously aggravating GL during a recent interview with TV Line.

"He's a jerk!," said the actor when asked what separates Guy from his fellow ring-slinging heroes. "What's important to know is, you don't have to be good to be a Green Lantern; you just have to be fearless. So Guy Gardner is fearless, and he is not very good. He's not nice, which is very freeing as an actor because you just think to yourself, what is the most selfish, self-serving thing I can do in this moment? And that's the answer. That's what you do in that moment. I think if he has a superpower, it might be his overconfidence, in that he thinks he could take on Superman. He can't!" 

Showrunner and executive producer Chris Mundy (via the WBD press site) recently assured fans that Lanterns won't "sacrifice the magic of the source material."

“From the start, our driving force has been to deliver a layered drama – rooted in nuanced storytelling and rich world building – that balances tension and mystery with honest, authentic emotion. The goal is to create something that feels timeless and grounded without sacrificing the magic of the source material.”

James Hawes (Slow HorsesPenny DreadfulThe Mist, The AlienistSnowpiercer) will helm the first two episodes. The creative team also includes Emmy Award-winning Lost and Watchmen creator Damon Lindelof, and comic book writer Tom King. Justin Britt-Gibson, Breannah Gibson and Vanessa Baden Kelly are also on board.

Lanterns "follows new recruit John Stewart and Lantern legend Hal Jordan, two intergalactic cops drawn into a dark, earth-based mystery as they investigate a murder in the American heartland.".

"This is a story of a couple of Green Lanterns John Stewart and Hal Jordan," Gunn said of the project when it was first announced. "We have a few other Lanterns peppered in there but this is really a terrestrial based TV show which is almost like True Detective with a couple of Green Lanterns who are space cops watching over Precinct Earth in it they discover a terrifying mystery that ties into our largest story of the DCU."
