post-production for "darkest night" lasted about one year, from june 2011 to june 2012 and took place in manila. work on this phase of production was delayed and severely hampered by strange events during this entire time. for example, all of the film's later dialog dubbing (adr recordings, see dubbing (filmmaking)) mysteriously disappeared at one point and were never found. also, much of the visual effects (vfx) footage and original sound effects recording, as well as footage of several chroma key screen shoots, all simply vanished. these types of disappearances plagued the film's post-production almost continually.
