The film's screenplay by Stephen Zotnowski was first used for a 2005 German movie production "Barfuss" ("barefoot" in German), meaning that this is, in effect, a virtual remake.
Kate Burton, who plays Scott Speedman's mother in this movie, played Ellis Grey, mother of Meredith Grey (Ellen Pompeo) in "Grey's Anatomy", in which Speedman appeared as a fling and love-interest of Meredith.
