Comedown (2012, IMDb link) starring Jacob Anderson, Adam Deacon, Jessica Barden, Duane Henry and Geoff Bell. Directed by Menhaj Huda.

The interiors on Comedown were mostly shot at Three Mills Studios on a superb set that dripped with atmosphere. So many gruesome scenes, but I think my pick is the nailgun. I really appreciated the extra ISO power of the Nikon D700 on this set, which for most of the time was barely lit at all; many of the interiors are shot at 3200 or higher.
