Okay, I lie, it's the volcano of Volcan de Agua, near Antigua, Sacatepequez in Guatemala.
Judkins is on a retreat with several other writers, including Amanda Kate Shuman who has written episodes of Chuck, The Blacklist, Berlin Station and The Following. This may just be a coincidence, or it may be a sign of other potential writers coming on board for the project.
With recent indications that the project is moving forwards (albeit slowly), with Sony Television working with an as-yet unannounced network/streaming partner, hopefully we'll get confirmation of the project soon.
Thanks to Narg at WoTTV for the heads-up.
