James Roy Horner (August 14, 1953 – June 22, 2015) was an American composer, conductor and orchestrator of film scores.

The score to the 1986 James Cameron film "Aliens" was composed by James Horner.
 The score itself includes musical references to Gayane's Adagio from Aram Khachaturian's "Gayane" ballet suite, which had been used in Stanley Kubrick's "" (1968).
 The score also uses musical motifs, sound treatments and excerpts from Jerry Goldsmith's original soundtrack to "Alien" (1979).
 Additional cues taken from Jerry Goldsmith's "Alien" score were used in the climax of the film when Horner was unable to finish some cues to Cameron's satisfaction.
 The film's editors also reportedly altered the score's chronological flow, sometimes looping, truncating or removing the music and placing it in fragmented form in the film out of context.
 Despite production issues, it was nominated for an Academy Award in 1986.
 It was performed by the London Symphony Orchestra.
 The soundtrack album was released the following year, in 1987.
K'inich Yax K'uk' Mo' (] "Great Sun, Quetzal Macaw the First", ruled 426 – c. 437) is named in Maya inscriptions as the founder and first ruler, "k'ul ajaw" (also rendered "k'ul ahau" and "k'ul ahaw" - meaning holy lord), of the pre-Columbian Maya civilization polity centered at Copán, a major Maya site located in the southeastern Maya lowlands region in present-day Honduras.
 The motifs associated with his depiction on Copán monuments have a distinct resemblance to imagery associated with the height of the Classic-era center of Teotihuacan in the distant northern central Mexican region, and have been interpreted as intending to suggest his origins and association with that prestigious civilization.
 One of the most commonly cited motifs for this interpretation is the "goggle-eyed" headdress with which Yax K'uk' Mo' is commonly depicted, seemingly an invocation of the northern central Mexican rain deity known as Tlaloc to later peoples such as the Aztecs.
 However, modern strontium isotope analysis of the human remains recovered from the tomb attributed to him indicate that K'inich Yax K'uk' Mo' spent his formative years much closer to Copán, at Tikal, and had not himself lived at Teotihuacan.
Swing Kids: Music From The Original Motion Picture Soundtrack is the soundtrack from the 1993 film "Swing Kids".
