Whitney Houston's first film, "The Bodyguard," in which she co-starred with Oscar-winning director Kevin Costner in 1992, not only earned more than $400 million at the box office worldwide, but was ultimately responsible for the biggest selling motion picture soundtrack album of all time. Featuring six Whitney Houston songs, the soundtrack has sold more than 34 million copies around the world. "I Will Always Love You," the first single from the album, became the largest selling commercial single in history, while three other singles from the album, "I'm Every Woman," "I Have Nothing," and "Run To You," have been major international hits for Whitney.
