The creators of CW's upcoming "Arrow" already have promised a grittier Green Arrow - Stephen Amell's Oliver Queen sports a leather-and-hoodie ensemble from Oscar-winning costume designer Colleen Atwood, and the world he inhabits on the new series premiering Wednesday is designed to believably be home to a rough-hewn vigilante. But that doesn't mean that the producers, including"Green Lantern's" Greg Berlanti and "Smallville's" David Nutter, are prepared to abandon the character's comic book roots - DC characters including China White, Huntress and Deadshot will get some screen time. And now it seems the Royal Flush Gang are on deck to shuffle things up as well. "Arrow" producers Marc Guggenheim and Andrew Kreisberg, DC Entertainment Chief Creative Officer Geoff Johns and star Amell met with reporters Monday to tout the new superhero drama and revealed that the costumed cadre of supervillains will stroll through Starling City. Their costumes, however, will be much less flamboyant and their powers less mystical than in comics. "You'll see with the Royal Flush Gang, that the dynamic of the family, and the iconography of the playing cards are going to be there, without the supernatural bent," said Kreisberg, a writer and executive producer of the series. I think we've come up with a really clever way to portray them in a more grounded, realistic world. The playing-card villains will make their debut in the sixth episode of the drama, with Currie Graham ("The Mentalist," "NYPD Blue") playing the leader of the gang, King. "We're really proud of that episode," Kreisberg said. We think it's one of the most successful attempts at alchemy that we've performed. Green Arrow first appeared in 1941, but viewers of the series won't necessarily need to know decades of comic book back story to appreciate the show, which will ponder the consequences of vigilantism even as Queen metes out his own brand of justice with bows and arrows in crime-ridden city streets. Given that, might another famous vigilante appear on the series? "Never say never" is all Guggenheim would say when asked about whether fans could expect a cameo from Batman - or, for that matter, Superman - though for the moment, a Bruce Wayne drop-in appears doubtful. "As much as we love bringing in DC comic characters, it's really important that this is a show about Oliver Queen," Kreisberg said. When you get too close to the naturally iconic characters like Batman and Superman, you're starting to suggest there is a bigger world outside of Starling City and, for right now, we want it to feel like Oliver Queen is the star of the show.
