Composer, arranger, and producer Harry Gregson-Williams began his career as a music instructor at the Amesbury School (where he worked with his brother Rupert) and the Guildhall School of Music and Drama in England in the 1980s. His meshing of electronic and orchestral styles has made him a highly regarded pioneer in the field of film scoring. Gregson-Williams works often with Tony Scott, having scored many of the director's movies since 1998's "Enemy of the State". He also worked multiple times with directors Dan Ireland, Joel Schumacher, and Ben Affleck. He was mentored by the film-music-industry heavy Hans Zimmer at Remote Control Productions (once known as Media Ventures) and has also produced worked for the Welsh band Hybrid. His most notable film scores have been for "Shrek", "Kingdom of Heaven" (where he utilized Arabian influences for the score), the big-budget remake of of the fantasy epic "The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe", and the video-game adaptation "Prince of Persia: The Sands of Time". Similarly, his kinetic and tech-enhanced touch has allowed him to extensively compose soundtracks for the gaming industry proper, with credits for the "Metal Gear" and "Call of Duty" series.
