Regency heads Down River, pre-emptively picking up the adventure thriller pitch from Sheldon Turner in a seven-figure deal.

According to The Hollywood Reporter, the story revolves around four twentysomething masters of the corporate world who decide to go on an actual adventure trip to the Amazon rather than on a high-class trip where you pretend to rough it. Things go awry when their tour guide is killed and the men have to face not only dangerous wildlife and tribesmen but also one another.

Turner (The Amityville Horror) came up with the idea for an adult Lord of the Flies after hearing stories of studio executives crowing about their annual "roughing it" nature trips that always ended up with the men retiring in the evenings to plush, Four Seasons-like lodgings.

No production dates have been set.
