The CW’s Wonder Woman prequel project is taking another step toward becoming a possible series.

Studio Warner Bros. has hired a casting director for the project and is preparing to send out a casting notice for the starring role. As previously announced, the project is titled Amazon and it “looks at the teenage years of the heroine who will become Wonder Woman.”

Normally casting doesn’t happen until after a project has received at least a pilot order — and Amazon, to be clear, does not. But a project like this so hinges on the lead role, perhaps the network and studio want to see some potential actors before deciding whether to pull the trigger (or they’re so confident it will receive a pilot order, they want to get a jump start on the casting process vs. competing pilot season projects).

Given the success of Arrow this fall, The CW must be tempted to add another DC Comics character to the lineup as a potential companion series. Just remember, however, we’ve been down this road before. Previously, NBC developed a Wonder Woman series last year starring Adrianne Palicki, but despite some photos that made us TV bloggers very happy, the project never made it past the pilot stage.

What do you think? Who should be cast as Wonder Woman — this time?

UPDATE: Looks like Deadline obtained the official casting breakdown, which has more details. The character’s name is Iris (5’8″ or above) and she comes from a secluded country where she was raised as a solider in a brutal environment. Now a stranger in a strange modern big city, she’s “a fierce warrior with the innocent heart of a romantic * and she will fight to the death to make the world safe.”

According to Deadline, this is the top-secret casting call for the lead in the new Wonder Woman drama. And as you can see the main character's name in this casting call is named Iris. But it was merely a ruse (or at least that's what The CW wants you to think), as Wonder Woman script writer Allan Heinberg took to twitter proclaiming, "Merciful Minerva! So much for using code names to avoid internet speculation. " Which we're assuming means, relax, she's still Diana.

She may rise again. The Wonder Woman origin drama Amazon is in active redevelopment at the CW. The project was originally written by Allan Heinberg last season. Despite doing some preliminary casting on the lead while the script was still being written, the network ultimately didn’t give it a pilot order, instead rolling it to off-season. A new writer, Heroes alum Aron Eli Coleite, was brought in. Now “we’re waiting for the script to come in,” CW president Mark Pedowitz said following the network’s upfront presentation today. “We do not want to produce something that doesn’t work for that character. It is the trickiest of DC characters to get done.” If the network likes the script, the project will be ordered as an off-cycle pilot. As for The Selection, it is “unlikely” the property will be re-visited again after two failed pilots, the second of which came close to a series pickup, CW brass said.

The CW no longer is developing the Wonder Woman prequel Amazon -- at least not right now.

Amazon was poised to explore the origin story of Wonder Woman's alter ego Diana of Themyscira. The network announced in September 2012 that it was teaming with Grey's Anatomy's Allan Heinberg to develop the story. The script was redeveloped in May, with Heroes writer Aron Eli Coleite taking a new stab at the story, and the network was poised to take the project to pilot for a potential off-cycle pickup. But that no longer will happen.

"We did not go forward with it," CW president Mark Pedowitz told The Hollywood Reporter following his Wednesday session at the Television Critics Association's winter press tour.

While Amazon will not move forward, Pedowitz was open to taking a second stab at the iconic Wonder Woman character if the right material were to come along.

"It all depends on the script. We were very careful with Arrow, and we're being very careful with Flash," Pedowitz said of the Stephen Amell series and Grant Gustin Flash pilot in the works at the network. "These are iconic characters, so we're going to be very careful with Wonder Woman. You only get one shot before you get bit."

Meanwhile, the network is developing DC's Hourman and iZombie with Rob Thomas (Veronica Mars) as it looks to expand its superhero roster. Beyond the youth-skewing network, Fox is prepping Gotham, a Batman prequel focused on Commissioner Gordon; NBC ordered Constantine to pilot; and ABC has found modest success with Marvel's Agents of SHIELD.
