That movie was Troy. They had around a week after Gabriel Yared was kicked off to score it and there wasn't any time for him to write all of it. It was mostly written by orchestrators including Conrad. He would just give them cues and he said to Conrad "write Horner".... And when Conrad said do you want to give me a theme or some cues to go by, he just allegedly replied, "No, you know what Horner sounds like" lol
