Composer James Horner earned a reputation in Hollywood for his emotionally stirring scores for some of the biggest films in movie history. Horner began his career in low-budget features for producer Roger Corman, and those assignments led to studio genre films, which culminated in his Oscar-nominated work on James Cameron's Aliens. By the ‘90s, Horner was among the top composers in the industry, penning scores for pictures like Titanic, which earned him an Oscar, and Avatar. Horner passed away in 2015 but will always be remembered as one of Hollywood's go-to maestros for blockbuster productions.
