As we learned in early June, Will Beall was hired to write a new superhero screenplay even before Marvel's big group hug was released.  It seems the script has gotten to a place where Warner. Bros is willing to show it to at least one director.  According to an update at Variety citing multiple anonymous sources, Affleck is the only possible director who has received the screenplay so far.

We don't know who else the studio might be considering for the job, but Affleck is reportedly at the top of that list, and he's expected to meet with some decision-makers to discuss the ensemble in the very near future.

This doesn't mean Affleck has the job or even wants it, but it does indicate some serious movement on Justice League.

Warner Bros. has been exceedingly keen on the director for some time now.  After enduring some crazy overexposure as an actor during the Naughties, the Good Will Hunting co-writer demonstrated serious directorial chops with Gone Baby Gone in 2007.  That film was distributed by Miramax, but when his follow-up, 2010's The Town, proved to be a to be a critical and commercial success for the WB, he's been a go-to guy for the studio.

The shot-callers at Warner Bros. previously tried to pair Affleck and Beall when it offered him the big gig on Gangster Squad, Beall's first produced feature script.  Affleck opted instead to star in and direct Argo, a darkly funny thriller centered on a real-life CIA exfiltration operation during the Iran Hostage Crisis.  That film is set for release this October 12th, and that the studio is willing to even consider Affleck for a task as expensive as Justice League suggests that Argo has turned out well. 

He's also been associated with The Stand, a massive adaptation of the Stephen King novel.  He might also star in Replay for the studio.  That film, based on the novel by Ken Grimwood, would be directed by Green Lantern producer and co-writer Greg Berlanti.

Unlike George Miller's Justice League: Mortal, which was abandoned shortly before production last year, this Justice League is going to happen one way or another.  The earliest we'll see it would be 2015, and it could even end up occupying the same summer as The Avengers sequel, which Joss Whedon just signed on to write and direct.
