1,200 theatres and earned Warner Bros. rentals in the United States and Canada of $7.7 million. It was considered a commercial failure. Score The musical score was composed by Academy Award winner Jerry Goldsmith. It used French horns and comparable instruments, which were intended to produce sound effects intended to resemble the sound of an apiary mega-swarm. The score originally was released on LP and cassette on Warner Bros. Records in 1978 at the same time as the film's release. An expanded, remastered score was released in 2002 in a limited edition by Prometheus Records and contained over 40 minutes of previously unreleased material. In 2020, La-La Land Records issued a two-CD set with the complete film score and the 1978 soundtrack album. Home media and alternate versions The film was originally released in theaters at 116 minutes, but when released on laserdisc in 1992, it was extended to 156 minutes with additional scenes. This extended version is also included on all DVD releases worldwide, alongside a 22-minute documentary, "Inside The Swarm", and the original theatrical trailer. It was first released to DVD by Warner Home Video on August 6, 2002, then reissued on January 28, 2016, under their Warner Archive Collection sublabel. The film was released on Blu-ray on September 25, 2018, again through Warner Archive. Like the two previous DVD releases, it contains the 156-minute extended version, the original theatrical trailer, and the 22-minute making-of documentary. In the U.S., the film was given a PG rating by the MPAA. In the U.K., the film was released with an A certificate in 1978. The BBFC rated the extended version 12. Disclaimer The ending credits to the film included a disclaimer that read: "The African killer bee portrayed in this film bears absolutely no relationship to the industrious, hardworking American honey bee to which we are indebted for pollinating vital crops that feed our nation." According to an article in HR published on February 24, 1978, the American Bee Association considered taking legal action against the film's producers for defaming the western honey bee, but whether the lawsuit was ever filed or not is unknown.
