Paul Wernick and Rhett Reese are the dynamic writing duo behind the phenomenon that is Deadpool. But it's not their first brush with unexpected success. One of their first movies was itself a surprise hit when it arrived in theaters way back in 2009, and Sony Pictures has been threatening a sequel ever since. Today, the Zombieland screenplay writers confirm that Sony is still very much intent on putting Zombieland 2 into production. Though when that will happen is not immediately clear.

Way back in September 2014, Sony reportedly became more serious about moving forward on Zombieland 2. At that time, they hired Dave Callaham to write the sequel script under the supervision of original director Ruben Fleischer. The belief has always been that Ruben Fleischer will return for this long-anticipated follow-up. Dave Callaham is known for his script work on The Expendables franchise and the American 2014 Godzilla reboot. But now, it isn't known if these two will be back, since so much time has passed between the release of the original and now.

It's also not known if the original actors plans to come back. Since Zombieland hit theaters in 2009, its entire main cast has gone onto bigger and better things, with Woody Harrelson, Jesse Eisenberg, Emma Stone, Abigail Breslin and Amber Heard all quite busy at this current moment in time. While some thought Zombieland 2 might be dead in the water, screenwriters Rhett Reese and Paul Wernick confirm that it is still very active at the studio. Speaking with The Playlist, they had this to say.

"It's actually still in development at Sony, they've had a couple writers take a crack at it, we're still exec producers and we're guiding and helping where we can and I think there's still very much talk about it, but I think it has to be right. I think all the actors and [original 'Zombieland' director] Ruben [Fleischer], all feel like there's no reason to do it again if we're not getting it exactly right."

Even with Zombieland 2 in development, Amazon launched a TV adaptation that brought the original characters (played by different actors) to the small screen. Most fans thought this version was atrocious and it was canceled shortly after the pilot debuted in 2013. The original Zombieland grossed $75.5 million domestically off a $28 million budget. It would go onto earn a worldwide gross of $102.3 million. At this time, no further information has been released about the story behind Zombieland 2. It's possible that it could revolve around a whole new group of zombie survivors.
