Afterwards, he created a duo of electronic music with Javier Navarrete, who worked and performed together from 1981 to 1986. He began working in film composition in the 1980s. Iglesias has composed a number of scores for films directed by Pedro Almodóvar, such as The Flower of My Secret (1995), Live Flesh (1997), All About My Mother (1999), Talk to Her (2002), Bad Education (2004), Volver (2006), Broken Embraces (2009) and The Skin I Live In (2011).

Iglesias garnered his first Oscar nomination for his score in Fernando Meirelles's film adaptation of The Constant Gardener (2005). Iglesias also composed the score for The Kite Runner (2007), based on Khaled Hosseini's 2003 novel of the same name. He earned his second Oscar nomination for that score.

In 2008, Iglesias composed Steven Soderbergh's 2008 two part biopic, Che (2008), starring Benicio del Toro as Che Guevara.

That same year, Iglesias composed the music for Tomas Alfredson's film adaptation of Tinker Tailor Soldier Spy, starring Gary Oldman as George Smiley. Iglesias told the Los Angeles Times, "(Alfredson) explained to me very well what this film is about. It's a film about loyalties and human relationships. Their spies are victims of this moment. That was the most important thing he told me. The film and the music show the more human side." He received his third Oscar nomination for the latter film.
