Factoids & Trivia

• Robert De Niro originally expected to make only a brief appearance, but his role was expanded and his scenes were filmed in about a week.

• Lions Gate Films created a promotional website for the fictional Godsend Institute, complete with contact information. Some bereaved visitors reportedly mistook the institute for a real service, leading the studio to clarify that it was only a movie tie-in.

• Five different endings were filmed. The version released theatrically was reportedly the least extreme.

• The operating-room scenes were filmed inside an empty swimming pool at the institute complex.

• Snow appeared unexpectedly during the cemetery sequence. The production chose to continue filming while the snow remained on the ground.

• The film's cloning premise placed it within a wave of early-2000s science-fiction horror that used genetic technology to explore grief, identity, and the ethical limits of scientific intervention.
