While promoting this film, Winona Ryder claimed that she and Keanu Reeves might actually have been married to each other in real life when they filmed the marriage scene in Bram Stoker's Dracula (1992), because a real Romanian Orthodox priest was used. Francis Ford Coppola, who directed that film, agreed that this could be true.
It was filmed in ten days.
The movie's alternate title is A Narcissist Can't Die Because Then the Entire World Would End.
This is the fourth film featuring Winona Ryder and Keanu Reeves, after Bram Stoker's Dracula (1992), A Scanner Darkly (2006) and The Private Lives of Pippa Lee (2009). In Dracula and A Scanner Darkly they also played a couple, but they didn't have any scenes together in The Private Lives of Pippa Lee.
