Trivia

This was the first film shot with Arriscope anamorphic lenses, which were created for Arri by the German manufacturer Isco-Optic.

Co-writer Stuart Gordon was originally set to direct, but was replaced by Abel Ferrara.

Body Snatchers is the third film adaptation of Jack Finney's novel, the first being Muertos vivientes (1956), followed by the remake of the same name Los usurpadores de cuerpos (1978). A fourth adaptation was later made, Invasores (2007).

Warner Bros. originally scheduled the film for release in October 1992. They opted for the more comedic Transilvania, mi amor (1992) as their horror release that season, as it was felt that the glut of serious genre fare such as Hellraiser III: Puerta al infierno III (1992), Candyman (1992), Dr. Bisturí (1992), and Drácula (1992) would overwhelm the film's potential. The release was moved around several times in 1993 before its unceremonious limited release came in January 1994.

Even though Marti and Jenn are supposed to be in high school, Gabrielle Anwar (Marti) was 23 years old when the movie came out and Christine Elise (Jenn) was 28.
