21-87 is a 1963 Canadian abstract collage film created by Arthur Lipsett that lasts 9 minutes and 33 seconds.

The short film, produced by the National Film Board of Canada, is a collage of snippets from discarded footage found by Lipsett in the editing room of the National Film Board (where he was employed as an animator), combined with his own black and white 16mm footage which he shot on the streets of Montreal and New York City, among other locations.

21-87 has had a profound influence on director George Lucas and sound designer/editor Walter Murch. Lucas's aesthetic and style was strongly influenced by it for the Star Wars films and a number of other works, including American Graffiti and his pure cinema short films "6-18-67", "1:42.08", "Look At Life", his short film Electronic Labyrinth: THX 1138 4EB and the feature it inspired, THX 1138. Lucas never met Arthur Lipsett, who committed suicide in 1986, but tributes to 21-87 appear throughout Star Wars to the extent that the phrase, "The Force", itself is said to have been inspired by the short film. In Star Wars Episode IV: A New Hope, Princess Leia's prison cell on the Death Star is 21-87.

Arthur Lipsett (May 13, 1936 – May 1, 1986) was a Canadian avant-garde director of short collage films.

In the 1960s he was employed as an animator by the National Film Board of Canada (NFB). Lipsett's particular passion was sound. He collected pieces of sound from a variety of sources and fit them together to create an interesting auditory sensation. After playing one of these creations to friends, they suggested that Lipsett combine images with the sound collage. The result is a 7 minute long film Very Nice, Very Nice which was nominated for the Academy Award for Best Short Subject, Live Action Subjects in 1962. Despite not winning the Oscar, this film brought Lipsett considerable praise from critics and directors. Stanley Kubrick was one of Lipsett's fans, and asked him to create a trailer for his upcoming movie Dr. Strangelove. Lipsett declined Kubrick's offer. Kubrick went on to direct the trailer himself; however, Lipsett's influence on Kubrick is clearly visible in the released trailer.

Edwin "El Chapo" Rosario (March 15, 1963 – December 1, 1997) was a Puerto Rican boxer. He was the WBC lightweight champion from 1983–84 and the WBA champion in 1986–87 and again in 1989–90. After moving up to the junior welterweight class, he became a WBA champion once more, holding the title from 1991 to 1992.

Chapo, as he was known in the world of boxing, was born in Barrio Candelaria, Toa Baja, an extremely poor barrio. Rosario's brother, Papo Rosario, was a professional boxer in the beginning of a promising career. His boxing manager and coach (trainer) was Manny Siaca Sr. that notice Rosario's talent since he was 8 years old. Rosario was inspired by his brother, and had a stellar amateur boxing career.

Papo died unexpectedly, supposedly due to drugs, two years after his brother's move to professional boxing. Rosario persevered, wanting to honor his brother's memory by winning a world championship. He scored big knockout wins over Young Ezzard Charles and Edwin Viruet, the former in 3 rounds on the Holmes-Cooney undercard. He eventually gained a record of 21-0 with 20 knockouts. This led to talks of a title fight against world lightweight champion Alexis Argüello, to be held in Miami, but Argüello abandoned the division to challenge Aaron Pryor.

Robert Edward "Bobby" Czyz (/ˈtʃɛz/ CHEZ; born February 10, 1962) is a retired American boxer. A New Jersey native of mostly Polish and Italian descent, he is both a former world light heavyweight and cruiserweight champion.

Czyz was born in Orange, New Jersey. He lived in Wanaque, New Jersey and attended Lakeland Regional High School.

Nicknamed "Matinee Idol", Czyz was a member of the United States amateur boxing team whose other members died in the LOT Polish Airlines plane crash in Poland in 1980. Because of an auto accident one week before the fatal trip, Czyz was not on the plane.

Czyz had a quick start to his professional boxing career in the early 1980s, and he was soon in line for a shot against world middleweight champion Marvin Hagler. He had to start from scratch, however, after suffering a 10-round loss at the hands of veteran Mustafa Hamsho in November 1982.

Czyz went up in weight, put another string of wins together, and in September 1986, he finally found himself in a ring with an undefeated world champion, IBF light heavyweight champion Slobodan Kacar (Olympic Gold medallist of 1980). Czyz beat him in five rounds.
