The film is mostly set in Moldova. Early in the film, the general remarks at one point that insurgents are near the Russian border to the north. However Moldvoa does not border with Russia at any point in its geography. It only borders Ukraine and Romania.
While no official explanation was given as to why the planned theatrical release was canceled, it has been speculated by insiders that Universal bailed on the release due to the large number of franchise-based Sci-Fi and action films being released in 2016 providing too much competition for an original property such as "Spectral", as well as Universal being leery over the project after the disappointing domestic box office of one of their other major 2016 releases, "Warcraft."
