Trivia: The corpse of Sid Shattuck, which Ryan Gosling discovers after his drunken roll down the hill, is played by an uncredited Robert Downey Jr., who'd previously starred in Shane Black's "Kiss Kiss Bang Bang", a film which played a large part in revitalising his career after drug and legal issues.
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."
