There is something I have always found odd about the soundtrack of John Carpenter's 1982 version of "The Thing". It has a very atmospheric and fitting, subtle synthesizer soundtrack, which is indeed very Carpenter-like. But in fact the soundtrack for this movie wasn't made by John Carpenter himself (although he often does it), but by Ennio Morricone, another famous soundtrack composer, but one who I personally wouldn't bring into relation with such a soundtrack.
So why did such a famous soundtrack composer like Morricone make a soundtrack so atypical for him but in fact more typical for Carpenter, who indeed often makes the soundtracks for his movies himself? Is there some interesting back-story behind this oddity or was it just the usual business?
