She stirs her tea. Then she warns that at the moment there is no script, no release date. There’s not even an official green light from the film’s releasing studio, Warner Bros.—and even if there were, nondisclosure agreements and her paranoia about jinxing things would keep her mum. “I really, really, really can’t talk about this,” she says, then gestures toward the restaurant’s picture windows, with their action-film-worthy Hollywood panoramas. “I just picture a drone coming in over the hills and crashing through the glass and flying over here and putting duct tape over my mouth, you know?”
The movie being discussed is, of course, Wonder Woman. The internet saw this and saw 'not even an official green light' and kind of began freaking out. Don't.
A movie gets a green light only when there's a script, and it's clear there's no script for Wonder Woman right now. A green light means the studio is now committed to putting the financing behind the project as outlined in a budget that comes from the script. Right now Wonder Woman is in what they call 'active development,' which means there's a team working on getting a script together to a point where everybody likes it and they can budget it out and the studio can then, finally, green-light the whole thing. This is pretty standard.
The one thing of interest is that MacLaren says (or is paraphrased as saying) there's no release date. This could mean that Warner Bros isn't entirely wed to the dates they previously announced - July of 2017. It could mean that MacLaren is hoping to move that date in order to continue working on development. It's not a bad sign in any real way, except to kind of prove that WB got ahead of themselves with their big DC slate reveal. Or it could mean the paraphrase is inaccurate.
When it comes to the script the big rumor is that WB has six writers working on six different scripts. That's a larger number of scripts that usual, but the latest thing in Hollywood when they have these movies they've dated but haven't developed is hire multiple people to work on scripts at the same time. They're not working together, and the idea is that in the end the studio will pick and choose - and possibly merge - from the different scripts. Warner Bros has two writers working on Aquaman scripts, for instance. Universal had two writers competing on The Mummy for their Monsters reboot. I don't know enough about union regulations to say much more, but I do know this is the sort of thing screenwriters hate, and which I imagine will lead to ugly arbitration in the future.
