Junkie XL (born 8 December 1967) and occasionally JXL, is a Dutch composer, multi-instrumentalist, DJ, producer, and engineer. Originally known for his trance productions, he has moved to producing electronica and big beat music and film scores. Junkie XL is best known for his remix of Elvis Presley's "A Little Less Conversation", which became a worldwide hit in 2002. In film scores, he is best known for his work in the DC Extended Universe beginning with Batman v Superman: Dawn of Justice with Hans Zimmer, contributing to the theme song for Wonder Woman, as well as the scores for Deadpool and Mad Max: Fury Road. In collaboration with Harry Gregson-Williams, he contributed additional music to the Tony Scott film Domino (2005), and served as the composer on the Dutch film Blind, which was nominated for Best Original Music Score at the Netherlands Film Festival in 2007 and received the Grand Prix award for Best Original Music Score at the 2008 Aubagne International Film Festival. Holkenborg continues to work in the film and television industry, collaborating with composer Hans Zimmer on Christopher Nolan's The Dark Knight Rises. The film marks the fourth scoring collaboration between Holkenborg and Zimmer, including Megamind (2010), Inception (2010) and Madagascar 3: Europe's Most Wanted (2012). Since moving into Zimmer's Remote Control Productions studio, the two have worked together on many other musical projects, including Man of Steel, the reboot of the Superman franchise, and a remix of that year's Academy Awards theme song. Holkenborg has provided music for the films Kingdom of Heaven, Domino, DOA: Dead or Alive, Shark Tale, The Chronicles of Riddick: Dark Fury, The Animatrix, and Resident Evil, and has had his original music featured in a number of major motion pictures, including Blade ("Dealing with the Roster") and The Beach ("Synaesthesia"). In 2013, he composed the music for the Relativity Media film Paranoia. Shortly after, he was brought in by Zack Snyder, the producer of 300: Rise of an Empire, to create the score for the film. He is credited as the composer for the 2014 film Divergent, with Hans Zimmer credited as "Executive Producer" for the soundtrack. He is a member of the Magnificent Six, a collaborative group of five other musicians, consisting of Hans Zimmer, Pharrell Williams, Johnny Marr (from The Smiths), Michael Einziger (from Incubus), Andrew Kawczynski, and Steve Mazzaro. The "supergroup" of artists ranging from diverse backgrounds teamed up to compose the score for the Marvel comic reboot's second feature film of the original Spider-Man trilogy The Amazing Spider-Man 2. He was the primary composer for the 2015 film Mad Max: Fury Road and the 2016 film Deadpool, and was co-composer for the film Batman v Superman: Dawn of Justice, along with Zimmer. Holkenborg's theme music for Wonder Woman was used in the film of the same name. Zimmer was replaced by Junkie XL to write and compose the music for Justice League releasing in 2017. Holkenborg later dropped out of composing the film in favor of Tomb Raider, and was replaced by Danny Elfman. On December 8, 2017, Holkenborg was revealed to be composing the score for the 2018 film Alita: Battle Angel, based on the manga Battle Angel Alita by Yukito Kishiro.
