Trivia: The film was originally produced by Universal pictures in association with Legendary Pictures with a planned theatrical release date in Summer, 2016. The film was then pushed back to a Fall release, before Universal suddenly opted to pull out of the project. Legendary subsequently sold the rights to Netflix, where it debuted as a Netflix Original Movie.
Trivia: 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."
