It was filmed in ten days.

This is the fourth film featuring Winona Ryder and Keanu Reeves, after Bram Stokeri Dracula (1992), Läbi hägu (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.

While promoting this film, Winona Ryder claimed that her and Keanu Reeves might actually have been married to each other in real life when they filmed the marriage scene in Bram Stokeri Dracula (1992), because a real Romanian Orthodox priest was used. Francis Ford Coppola, who directed that film, agreed that this could be true.

In real life, Winona Ryder and Keanu Reeves have been friends since the 1980s.

Winona Ryder (Lindsay) and Keanu Reeves (Frank) hold the only on-screen speaking roles in the movie. Movies playing on the TV in their rooms and announcements made over PA systems are the only other voices heard.

The film wasn't announced until after it had already finished filming and entered post-production.

The movie's alternate title is A Narcissist Can't Die Because Then the Entire World Would End.

Shot almost entirely in master or 2 shots with no close up coverage.

The first movie Frank and Lindsay are watching on their separate TVs is "Scarlet Street" (1945) with Edward G. Robinson.

John Wayne Bobbitt was mentioned by Lindsay when she was teasing Frank about his wine-stained pants. Bobbitt made headlines in 1993 when his wife. Lorena, cut off his penis.

When discussing his parents at the rehearsal dinner, Franks alludes to his father's new girlfriend "being a senior while he was a freshman," which is near identical to a quote from Bill & Ted's Excellent Adventure.

In one scene, Winona Ryder's character mentions to Keanu Reeves character, Frank, "Let's play Devil's Advocate". "Devil's Advocate was the title of Keanu Reeves 1997 movie of the same name.

Winona Ryder and Keanu Reeves may "think" they were married in "Bram Stoker's Dracula", but it was consummated in "Destination Wedding", 26 years later.

Although others have suggested that Keanu and Winona may have been married in a Sacramental sense because an actual Orthodox priest was used in the scene in Dracula (1992), this is not the case at all. The president (or "officiant") is merely an official witness, although to be "official" he must be an ordained member of the clergy. It is the couple that marry one another, not the officiant that "marries" them. Besides, as another entry mentions, their "marriage" was not consummated until Destination Wedding (2018), 26 years later, so if was truly a concern for them, they could have/should have had their faux marriage reviewed for annulment (for non-consummation, which automatically invalidates a "marriage") before shooting this picture.

Lindsay's address is 14 Catalina Drive, Newport Beach.

Only Keanu Reaves and Winona Ryder have speaking lines throughout the entirety of the movie
