Professional purveyor of both OrchestralBombing and {{Award Bait Song}}s. Wrote the score for numerous films, working alongside Creator/JamesCameron for three of his most successful films. He composed the scores for many family and AnimatedFilms before his commercial success scoring ''Film/{{Titanic}}''.

Most of his work is known for his incorporation of the EtherealChoir and Celtic instruments, as well as synth sounds. However, listeners tired of his "cute" sound, heard most prominently on his scores for ''Film/{{Titanic}}'', ''LegendsOfTheFall'' or ''Film/{{Avatar}}'', can find much more exciting (and seminal) material in his music for ''Film/StarTrekIITheWrathOfKhan'' (his breakthrough within the industry), ''Film/{{Krull}}'', ''Film/{{The Rocketeer}}'' and ''Film/{{Willow}}''. The latter is one of the firsts to include previously mentioned musical elements, but your pants will fall down the floor once you listen to something like [[http://youtu.be/GcMOTVY3CUU?t=1m13s this]] and compare it with the mushy ethereal vocals he's most famous for.

Known somewhat less fondly for reusing his music from previous films. Also along these lines, he has a habit of directly quoting themes and motives from 20th century Russian masters.

!!Some of his scores include (reverse chronological order)
* ''Film/TheAmazingSpiderMan'' (2012)
* ''Film/TheKarateKid'' (2010)
* ''Film/{{Avatar}}'' (2009)
* ''Film/{{Apocalypto}}'' (2006)
* ''Film/{{Troy}}'' (2004)
* ''Film/ABeautifulMind'' (2001)
* ''Film/ThePerfectStorm'' (2000)
* ''Film/TheMaskOfZorro'' (1998) and its sequel, ''The Legend of Zorro'' (2005)
* ''Film/{{Titanic}}'' (1997) - The defining film for Horner, much like StarWars for JohnWilliams.
* ''WesternAnimation/{{Balto}}'' (1995)
* ''Film/{{Jumanji}}'' (1995)
* ''Film/{{Apollo 13}}'' (1995)
* ''Film/{{Casper}}'' (1995)
* ''Film/{{Braveheart}}'' (1995)
* ''LegendsOfTheFall'' (1994)
* ''WesternAnimation/ThePagemaster'' (1994)
* ''WereBackADinosaursStory'' (1993)
* ''HocusPocus'' (1993) - with John Debney (Horner did one theme while Debney did the rest of the film)
* ''OnceUponAForest'' (1993)
* ''Film/TheRocketeer'' (1991)
* ''{{Glory}}'' (1989)
* ''FieldOfDreams'' (1989)
* ''Film/HoneyIShrunkTheKids'' (1989)
* ''Film/{{Willow}}'' (1988)
* ''TheLandBeforeTime'' (1988)
* ''WesternAnimation/AnAmericanTail'' - (1986) Also its sequel ''Fievel Goes West'' (1991). It was the first score that won him some awards.
* ''Film/{{Aliens}}'' (1986) - He had such a hellish time scoring this due to the movie's famously troubled production and initially swore he'd never work with Cameron again. However, he relented on this, and had better experiences with the other Cameron movies.
* ''Film/{{Krull}}'' (1983)
* ''Film/StarTrekIITheWrathOfKhan''' (1982) and ''Film/StarTrekIIITheSearchForSpock'' (1984). Star Trek II was his big break and launched him into the Hollywood scene; he later declined the offer to score later Trek movies. Debate still rages over whether his or JerryGoldsmith's music is superior.
** Nicholas Meyer famously quipped that Horner was hired for ''Khan'' because they couldn't afford Goldsmith again, and then when he returned for the sixth film, he discovered he couldn't afford Horner.
* ''Film/BattleBeyondTheStars'' (1980) - Ironically considering his later career, music from this film would be used in several other Roger Corman productions (''Space Raiders'', ''Sorceress'', ''Wizards Of The Lost Kingdom'' etc).[[note]]Conducted by DavidNewman.[[/note]]

!!Works for television include:
* ''Series/AmazingStories'' ("Alamo Jobe")
* ''CBS Evening News With Katie Couric'' (yep, that was him)
* ''WesternAnimation/FishPolice'' (he not only did the theme for this short-lived cartoon, he also did one of his very few episodic TV scores for the pilot)
