Speaking during an interview with Game Developer, Metal Gear Solid 2: Sons of Liberty music producer Rika Muranaka revealed that Hideo Kojima had originally wanted to get Hans Zimmer to composer the score for the iconic PlayStation 2 stealth-action sequel.
Unfortunately, Zimmer was a bit too expensive for the team, so they went with Harry-Greyson Williams instead — who obviously went on to do an utterly brilliant job.
We went to Media Ventures (now known as Remote Control Productions), which is Hans Zimmer’s studio. We originally wanted to get Hans Zimmer, but he was like ‘No, I can’t do it for that kind of money’-he’s so expensive, it’s ridiculous. So Hideo asked me to try and get in touch with Harry, because Harry was working for Hans Zimmer too in that studio at that time.
At that time, he was still an upcoming composer, but he had done Enemy of the State, so a lot of people had started to notice him.
Metal Gear Solid 2: Sons of Liberty was released in Japan and the US for the PS2 in 2001, and made its way to Europe the following year.
